It may be an inn on a road in a HeroicFantasy world, a [[TheWildWest Wild West]] saloon, a bar in a [[TheFuture high-tech space station]], or just a [[MyLocal local pub]] -- or it could be all of these ''at the same time''. The Inn Between the Worlds exists simultaneously in different worlds, universes and/or times, or perhaps just jumps around in the fashion of TheLittleShopThatWasntThereYesterday. Whether you can reliably return to where you came in varies.

Inns Between The Worlds, though they connect to some or all worlds, are ''not'' themselves part of ''any'' world. They are typically [[TruceZone places of truce]] and/or sanctuary, and laws of physics and/or reality may be suspended as needed. (Quite a lot of them, for instance, are BiggerOnTheInside.)

Sometimes Inns are used as a FramingDevice for the patrons to tell strange and fantastic stories of their worlds. Sometimes it enables a TimeTravel or TrappedInAnotherWorld plot, where the character leaves the inn through the wrong entrance (or the ''right'' entrance depending on your point of view). Perhaps it enables a {{Crossover}} for characters from different worlds or times [[GoodGuyBar to meet in a friendly environment]]. On rare occasions, if no one ever leaves, it may turn out to be a kind of [[DeadToBeginWith afterlife]].

!!Compare with:
* TheLittleShopThatWasntThereYesterday: Also an island of the fantastic in the ordinary world, but Inns don't move around as much, are much more social than Little Shops (where your interactions are almost always limited to a single shopkeeper), and are less focused on the acquisition of magical items.
* BazaarOfTheBizarre: More social than Little Shops but less than the Inn. The Inn is also not particularly focused on commerce (except food, drink, and sometimes rooms).
* AtTheCrossroads: The Crossroads are where roads meet. The Inn is where universes meet.
* PortalCrossroadWorld: A world (or city etc.)existing in one universe, but containing access to many others.
* GoodGuyBar (or BadGuyBar)

!!Contrast with:
* VoidBetweenTheWorlds: When there's nothing outside reality.
* EldritchLocation: A place outside reality that ''isn't'' hospitable.

!!Examples

[[foldercontrol]]

[[folder:Anime and Manga]]
* The {{Nasuverse}} has the Cafe Ahnenerbe, a rustic little restaurant noted for its excellent curry, is noted as a "place of impossible meetings" since it connects to all dimensions of the {{Nasuverse}}. The end results of the meetings can be, [[Anime/CarnivalPhantasm well...eccentric]]. The one to blame is (as always when it comes to [[TheMultiverse dimensional travel]]) [[VisualNovel/{{Tsukihime}} Zelretch]].
** The Ahnenerbe is an accessible restaurant in ''Literature/KaraNoKyoukai'', but in Episode 5 it gets used this way when [[spoiler:Tomoe and Shiki]] say their farewells to each other at the end of the movie.
[[/folder]]

[[folder:Comic Books]]
* Book 8 of ''ComicBook/TheSandman'' (''Worlds' End'') is set in the titular extra-dimensional inn. Book 9 mentions that there are a total of four, although only one of the others ("The Toadstone") is named.
** One of the ''ComicBook/HouseOfMystery'' comics from Vertigo is set in one of these. It doesn't count as one of the four, because it was set up as a bar some time after the events of ''Sandman''.
** The second to last act of ComicBook/TheBooksOfMagic takes place in there.
* TabletopGame/{{Warhammer}} has a comic series called ''Tales of the Ten-Tailed Cat'' set in a tavern like this.
* The Oblivion Bar in ''ComicBook/{{Shadowpact}}'', formerly a bookstore.
* Munden's Bar in ''Grimjack''; in this case, it's a property of the ''city'' the bar is in, though Munden's itself gets more than its share of odd customers even by the standards of Cynosure.
* The ''Franchise/{{Transformers}}'' comics had Old Maccadam's Oil House, one of the best bars on Cybertron. It's run by the eponymous Maccadam, who is rumored to be one of the original thirteen Transformers (and thus a multiversal nexus in and of himself), and in one comic one of the backrooms served as a hangout for dead Optimuses from across the multiverse while they were waiting for resurrection. As soon as the Optimuses (Optimi?) got revived, a gaggle of dead Megatrons showed up. Notably, except for the dead Optimi and Megatrons, its patrons are unaware that they're dining in a cross-multiversal establishment.
* The Crossroads from ''ComicBook/SovereignSeven'' is a coffee shop version of this.
[[/folder]]

[[folder:Commercial]]
* Sony made [[http://www.youtube.com/watch?v=mdWkKKSckNk one]] that has various game characters hang out in a bar, who all end up cheering the player for being a great person who helped them in their time of need.
[[/folder]]

[[folder:Fan Fiction]]
* ''FanFic/ThisTimeRound'', the ''Series/DoctorWho'' pub outside continuity, [[GoodGuyBar a meeting place for everything]] in the ''Franchise/DoctorWhoExpandedUniverse'' - and every canon they've crossed over with. Inspired by the Subreality Cafe, which is this for comics characters.
* [[FanficRecs/MegaCrossover Arisugawa's Locket]] also exists simultaneously across many dimensions.
* The open story Tales From the Barman (parts I and II) on Twisting the Hellmouth is set in a variant of this: Xander opens a bar in Cleveland, but given the local Hellmouth and the usual clientele of Slayers, demons, witches, etc. quickly becomes a multi-dimensional nexus, with every chapter being a new character or set of characters passing through and Xander trading drinks for stories.
* ''[[FanFic/NewLookSeries Link's New Look]]'' has The Smash Mansion, where every member of the VideoGame/SuperSmashBros series (and hence, Nintendo characters from wildly varying universes) co-exist.
* In the early times of the ''WesternAnimation/ChipNDaleRescueRangers'' fan forum Acorn Cafe, the Ranger Coffeehouse was established, a place where FanFiction characters hang out when they aren't busy in a fic. This includes characters from the show itself, and as fanfics tend to [[DependingOnTheWriter portray them differently]], multiple instances of them are likely to meet each other. The Ranger Coffeehouse is located on the Dragon Planet and can be accessed via interdimensional portals. Also, the love of the Rangerphiles at the Acorn Cafe for roleplays and [[RoundRobin Round Robins]] has been taken into account: Self-insertion characters[=/=]fursonas ("Creators") are denied access to the Coffeehouse.
[[/folder]]

[[folder:Film]]
* [[WreckItRalph Wreck-It Ralph]] has Game Central Station, which is a surge protector that connects all the arcade machines together in reality, but serves as this for the game characters.
[[/folder]]

[[folder:Literature]]
* The Leaky Cauldron from ''Literature/HarryPotter'' qualifies. It's not in the Muggle world (Muggles can't see it) nor really in the wizarding world (it's in Muggle London), and leads to a portal between the two.
* ''Literature/CallahansCrosstimeSaloon'' and sequels feature an inversion, the pub is pretty ordinary. It's the patrons [[spoiler:and barkeep]] that come from everywhere and everywhen.)
** ''Lady Callahan's'' is similar, but it is a brothel with a bar downstairs. Oddly, the innocent and regulated downstairs is so awesome that some never take advantage of the other services available.
** Ditto with Creator/ArthurCClarke's ''Tales from the White Hart,'' Creator/LSpragueDeCamp's ''Tales from Gavagan's Bar,'' and Creator/LarryNiven's ''Tales from the Draco Tavern.''
* ''The Captain's Table'' ''Franchise/StarTrek'' novels use it as a FramingDevice. This particular version can only be reached by those who hold [[strike:or have held]] the Captain rank (or its equivalent) which, coupled with the fact it touches all of time and space, means [[GoodGuyBar it sees all sorts of visitors]] -- like a Captain of a Roman Legion. About the only permanent occupant (other than [[EveryoneCallsHimBarkeep Cap, the Bartender]]) is a dazed man in a tattered uniform who sits in a dark corner staring into nothing and mumbling about icebergs... yes, that's right, it's Captain Edward J. Smith of the ''Titanic'', who remains in the Captain's Table due to a mixture of having suffered a mental breakdown and the fact that stepping out the door will place him back on the ''Titanic'''s deck as it finishes sinking into the ocean. It looks like whatever the particular captain thinks a bar should look like, and Cap always knows ''exactly'' what each patron wants to drink.
* Milliways, the Restaurant at the End of the Universe from ''Franchise/TheHitchhikersGuideToTheGalaxy'', after a fashion. In ''Literature/TheRestaurantAtTheEndOfTheUniverse'', due to their unusual form of travel to the titular eatery, the heroes briefly believe they're dead, and seriously consider the consequences of the afterlife being a fancy restaurant.
** Also the MassiveMultiplayerCrossover [[http://www.community.livejournal.com/milliways_bar LiveJournal .]] RPG named for it, although whether they're actually meant to be the same bar is unclear.
** And don't forget the Big Bang Burger Bar, at the ''other'' "end" of the universe...
* Played with in Phyllis Ann Karr's ''A Night at Two Inns'' in the second of the ''Sword and Sorceress'' anthologies, where there are not one but ''two'' such inns opposite each other. Each claims to be Heaven, and denounces the other as Hell. [[spoiler: Actually, one was a Valhalla-type afterlife and the other a contemplative one -- but the residents of either would find the other hellishly unpleasant.]]
* The 1988 Hugo-Winning short story "Why I Left Harry's All-Night Hamburgers" by Creator/LawrenceWattEvans features a hamburger joint that exists in the same spot in nearly all universes, making it a popular late-night hangout for inter-dimensional travelers.
* Creator/AlfredBester & Creator/RogerZelazny's ''Psychoshop'' has a similar nature, but instead of a bar, it's a sort of pawnshop, "where you can dump any unwanted aspect of your spirit as long as you exchange it for something else".
* The Old Phoenix Tavern in several works by Creator/PoulAnderson, most famously ''Literature/AMidsummerTempest'' -- where it introduces a character from his ''Literature/OperationChaos'' and another from ''Literature/ThreeHeartsAndThreeLions''. (This enables Anderson to tell curious readers what happened to the hero of the latter, without writing a full-scale sequel).
* The short story ''The Inn at Mount Either'' takes place at an inn located on an inter dimensional mountain and is connected to alternated versions of itself. The story deals with the protagonist searching for his wife after she gets lost among the infinite worlds. It is implied that the wife he found wasn't "exactly" who he was looking for, and he may have not returned to the right Earth.
* The Draco Tavern in several Creator/LarryNiven short stories is a pub in Earth's main spaceport, equipped for a ''very'' [[GoodGuyBar diverse range of customers]].
* In Creator/StevenBrust's novel, ''Cowboy Feng's Space Bar And Grille'', the titular eatery jumps from world to world (and time to time) whenever an atomic bomb goes off nearby. And that's been happening a lot lately...
* The House of Red Fireflies is a brothel between the worlds, currently there are [[http://ursulav.livejournal.com/443439.html three]] [[http://ursulav.livejournal.com/468493.html short]] [[http://ursulav.livejournal.com/777952.html stories]] set there.
* Honest John's in ''TheRiftwarCycle''. It's reached from the [[PortalNetwork Hall of Worlds]], by stepping off the path ''between'' certain doorways. You have to know the right spots... ''or else''.
** Any of the several ''right spots''. Or else ''what'' is never really elaborated upon, but nobody ever comes back from it. Nobody ever says how, exactly, it was found, or for that matter how it exists.
* This isn't exactly the case of Hotel Babylon in ''Literature/DeepSecret'', but it does bend the laws of physics (like you could make seven right hand turns and still not end up where you came from) since enchanters keep using magic and opening portals to other worlds from there.
* A. Bertram Chandler once had Space Navy officer John Grimes inadvertently cross universes to a club for fictional naval personnel -- though the original rules were bent a bit to allow non-naval ship captains such as [[MobyDick Ahab]] to hang out there (it's hinted that [[Franchise/JamesBond Commander Bond]] had to strong-arm [[TheCaineMutiny Captain Queeg]] somewhat to make him stop objecting to Ahab's inclusion). [[TheJeeves Jeeves]] is the chief servant at the club, is fully aware of the fictional nature of all involved, and asks Grimes (approximate quote): "The question is, sir, are you an ''enduring'' creation?"
* SergeyLukyanenko's novel ''Literature/RoughDraft'' is about a regular guy who ends up being erased from reality and become a "[[DifferentlyPoweredIndividual functional]]", a not-quite-human being with a specific function and certain superhuman abilities to better perform said function. In the protagonist's case, he becomes a sort-of customs officer. His "function" is to be in charge of an interdimensional building, which is also his new home. In our world (Earth 2 or Demos), the building appears as an old water tower near a railway station. The tower can create certain objects of comfort based on the functional's will. The doors on the first floor all lead to other worlds. Only the resident customs officer can open them. The trick is, nobody knows where the doors will lead before they open for the first time. The customs officer can charge people tariffs for certain restricted items and keep the money. It's very difficult to destroy a tower. One way is with a [[spoiler:thermonuclear device]].
* ''Deadfall Hotel'' by Steve Rasnic Tem focuses on this trope; a hotel where monsters and ghosts can seek peace and solitude.
* ''Powers'' by James Burton has the palace/room with doors opening onto different places, times and dimensions.
[[/folder]]


[[folder:Live Action TV]]
* The "Astral Diner" of the ''Series/StargateSG1'' episode "Threads". The place is a midway point between the mortal dimension and the higher realms where the Ascended live. Played with in that it's actually an example of AFormYouAreComfortableWith, as it was modelled after Daniel Jackson's memories.
* Arguably, Al's diner/bar in Mirror Image, the last episode of ''Series/QuantumLeap''.
* The eponymous diner of ''Series/NightmareCafe'' was an example of a sentient Inn Between The Worlds.
* Hikari Studio in ''Series/KamenRiderDecade'', which serves as Tsukasa's method of travelling between the parallel worlds. It is technically a photo studio, but as Natsumi's grandfather Eijiro is fond of making food and coffee for whoever wanders in, it effectively functions as a cafe as well.
* The pub in ''Series/{{Life On Mars|2006}}'', as revealed in ''AshesToAshes'', is actually [[spoiler: the door between heaven and purgatory.]]
* On ''Series/{{Fringe}}'', [[spoiler: the building on Liberty Island where the machine is kept]].
[[/folder]]

[[folder:Tabletop RPGs]]
* Sigil from the ''{{Planescape}}'' [[DungeonsAndDragons D&D]] setting is the city equivalent of this trope -- located on the inside of a torus on top of an infinitely tall spire located in the exact center of the planes (who are infinite in size -- no, don't think too hard about that one), it is simultaneously connected to almost everywhere in D&D cosmology through its virtually infinite amounts of portals, all of whom differ in size, place they lead to and what opens them. Because of this, Sigil is a place where one can expect to find almost anything. It's still a somewhat normal town with everyday life and time that flows normally, however. Well, as much "normal" as can be a city built on the inside of a torus so that you can see it curving above you, where belief can shape reality, visited every day by strange creatures from all over the multiverse, ruled by an enigmatic being who kills those who worship her by pulling her sharp shadow over them...
** The World Serpent Inn mentioned in several ForgottenRealms {{sourcebook}}s was built in its own demiplane by an archmage from [[ForgottenRealms Toril]], [[{{Spelljammer}} Arcane]] and [[{{Cthulhumanoid}} Illithid]] as a [[TruceZone neutral ground]] when Sigil turned out to be too violent and inconvenient for quiet business and rest. Not only is it connected to many worlds, but (unlike Sigil) is accessible to powers, and some gods visit it to relax and chat with creatures they deem interesting. It's a form of GoodGuyBar, since no one wants to annoy peacefully grazing deities, and some clients in a common room ''can'' turn out to be gods on a tea-break. And even if there aren't any, TheBartender is an avatar himself--if some god just likes to meet new people and thinks it's funny, why not?
** The ''DungeonsAndDragons'' ''Mystara'' campaign world has '''two''': the ''Comealong Inn'' and ''The Inn Between the Worlds''. (Originally just one, they were split thanks to a {{Retcon}}.) Other campaign settings have the World Serpent Inn, which is actually theorized to be a [[GeniusLoci sentient demi-plane]].
** Among the many, many items in the 2nd Edition Encyclopedia Magica is the "Awl, Inn", a cobbler's tool that could be used to open a portal to such an Inn.
* Terra City, from ''[[TheChroniclesOfFate Chaos]]'', is more of a [[WhatDoYouMeanItWasntMadeOnDrugs Multiverse-sized ecumenopolis-city between the worlds]]. Warriors, wanderers, travelers, traders, troubadours, and every other sort of strange folk come and go here every day from the most distant multiverses. It's probably not hard to guess that Terra City has hundreds of septillions (at a low estimate) of bars, inns, pubs, watering holes, and other, much stranger types of establishments, different ones of which are popular with beings from different parts of the omniverse.
* Several roleplaying forums have an Inn Between the Worlds or similar subforum for players to meet up and chat in character despite [[GoodGuyBar playing in different campaign worlds]].
* There is a ''{{GURPS}}'' worldbook where every adventure starts in a bar where going to the bathroom can land you literally anywhere in the multiverse.
** GURPS also has a semi-sentient Victorian Era-esque Gentleman's Club which has hundreds of doors which all lead to various alternate universes, listed in the original Time Travel supplement.
** And the newer Infinite Worlds books gives a brief mention of the Infinity Patrol bars. The patrons might all be from the same world, but they've been just about everywhen.
* The eponymous Floating Vagabond from the RPG ''TalesFromTheFloatingVagabond'' is a variation of this--it only ''exists'' in one place and time, but has a device that will randomly cause people who enter other bars in any time, reality, or location in the universe to end up there... and once it's happened once, they can ''intentionally'' cause it to happen whenever they enter another bar from then on.
* "Chez Régis" in ''TabletopGame/InNomine Satanis''/''Magna Veritas'', where angels and demons can [[GoodGuyBar drink without fighting each other]].
* Though not precisely between worlds, the Hollows that characters in ''TabletopGame/ChangelingTheLost'' can build do share characteristics with this trope: Built in a parallel dimension called the Hedge, a Hollow can, and usually will, open into both worlds, and its doors can be separated by vast distances in Earth-side terms (a Hollow could have entrances in Boston, London, Tokyo, and Moscow fairly easily).
[[/folder]]

[[folder:Video Games]]
* The Quester's Rest in ''VideoGame/DragonQuestIX''. It is visited by several {{cameo}} characters from previous DragonQuest games; and you can meet with and travel with AlternateUniverse versions of yourself. (IE, other players who have the game.)
* "Pocket D" is a [[GoodGuyBar nightclub]] in a small PocketDimension, in the {{MMORPG}}s ''CityOfHeroes'' and ''City of Villains'' (and ''City of Heroes Going Rogue''). It's accessible from multiple points in either games, and allows characters from all three to interact in a neutral environment (CoH and CoV have multiple PvP zones otherwise).
** It's also the designated location for special events, including the [[HolidayMode Winter and Spring]] Events.
*** Does this really count though? Both the rogue isles and Paragon city, last I checked were in the same universe.'
**** Pocket D is called "Pocket D" as an abbreviation for "Pocket Dimension." It's not anywhere on Earth, or even the same plane of existence as Paragon City and the Rogue Isles.
* In the earlier part of ''VideoGame/ChronoTrigger'' but (suspiciously) right after the number of characters playable at once exceeds three, time travel happens through portals at the "End of Time", which is a claustrophobic collection of several connecting rooms. It's not nice enough to be an Inn, but it ''is'' an important juncture point between the eras of time.
** There is [[HandWave some kind of explanation given]] about why you end up there to justify why it happened only as you got four characters in your team.
** The fact that it's the juncture point ''between'' points of time is hilarious when you remember that it's the ''end'' of time. In other words, the fastest way between two points of time is to go to the end and back.
*** This isn't as surprising when you take into account the fact that the "End" of Time is really just a convenient moniker for a place that simply exists outside of time. It's easy to travel between points in time when you simply exit the continuum and re-enter it at a point of your choosing.
*** Nor is it meant to be the fastest way. It's little more than a temporal divide-by-zero error. (Remember how in ''WildArms'', you would get to the Abyss by beating the crap out of the teleporter?)
* The aptly-named Tavern of Time, located in the Caverns of Time in VideoGame/WorldOfWarcraft. It's simply a little house with a bartender [=NPC=] in it. The "between the worlds" part comes from the fact that the Caverns of Time are the home and workplace of the [[TimePolice guardians of time]] and nearby [=NPCs=] are UnstuckInTime.
** The mage's tower in Stormwind contains a portal leading to large room with tall Cathedral ceilings, where the mage trainers do their studies. If you listen to some of the mages' conversations around the district, they talk about stabilizing portals and creating small universes.
* Traverse Town, in ''KingdomHearts'', serves as a refuge for survivors from all the different worlds that've been destroyed by TheHeartless, and a launching point into the game's [[TheMultiverse multiverse]]. The "corridors of darkness" that are ripped open during a world's destruction tend to take people to Traverse Town by default, which is how the hero first arrived after escaping his DoomedHometown.
* The ''Franchise/ShinMegamiTensei: VideoGame/{{Persona}}'' series has the "Velvet Room," a sort of cabaret lounge located "between consciousness and subconsciousness". It can only be entered by those who possess a connection to the spirit world.
* In the ''VideoGame/GoldenSun'' series, there is an arena that you are able to go to anywhere from the main menu. The characters inside seem to acknowledge its existence, yet it is never visited in the main game of either of the games.
* The Cafe of Broken Dreams in ''VideoGame/{{Fallout 2}}'' is the fourth-wall breaking version of this. It's a random encounter, but if you get it, you meet up with the [=NPCs=] of the first game, engage in jokes about character models, and get Dogmeat back.
* ''VideoGame/SuperPaperMario'' has the towns of Flipside and Flopside, which are said to exist between dimensions.
* ''VideoGame/FinalFantasyV'' has a stranger than usual example in a town that disappeared out of existence for centuries, [[spoiler: only to reappear when two worlds were rejoined into the one on which the town was built. It gets even stranger during a sequence that takes you through nearly every location in the game via... [[AppliedPhlebotinum dimensional compression]]... with the town and its inhabitants being frozen in place, and a previously sealed door now serving as another interdimensional portal.]]
* The Inventory from the ''VideoGame/PokerNightAtTheInventory'' games, which has thus far hosted (or employed) characters from ''VideoGame/{{Borderlands}}'', ''VideoGame/SamAndMaxFreelancePolice'', ''VideoGame/TeamFortress2'', ''VideoGame/{{Portal}}'', ''WebAnimation/HomestarRunner'', ''Webcomic/PennyArcade'', ''Franchise/EvilDead'', ''WesternAnimation/TheVentureBrothers'', and ''VideoGame/MonkeyIsland'' (supporting character Reginald van Winslow runs the place). Characters from ''VideoGame/GravityBone'' and ''VideoGame/TheWalkingDead'' have made cameos.
-->'''Max''': Whatever happens in the omnidimensional accretion nexus, ''stays'' in the omnidimensional accretion nexus.

[[folder:Web Comics]]
* In ''{{Achewood}}'', travelling between Earth and Hell is done through the restrooms in Friendly's.
* ''Webcomic/TheAdventuresOfDrMcNinja'' shows Purgatory as being a Restaurant Between the Worlds, in which one eats one's venial sins to purge them from the soul. However, since the restaurant is infinite and there's only one waiter, the process can take millennia.
* ''The Webcomic/CrossTimeCafe'' webcomic exists to let webcomic characters meet up outside their own continuity.
* The Pub Stub from ''{{Goats}}''.
* The shop Phantasies in Webcomic/IncubusTales is a prime example of this.
* The proto-strips of ''Webcomic/{{Roommates}}'' took place in an unnamed Inn Between Worlds and also it's 'verse could be seen as this scaled up to town (if not planet) size, where [[MegaCrossover every fiction in existence has a back door to]]. Welcome to the ''{{Franchise/Buildingverse}}''.
* ''{{Webcomic/Subnormality}}'''s [[http://www.viruscomix.com/page533.html "Museum of the Theoretical"]] is a meta-fied edition of this trope.
* ''[[https://www.tigerdile.com/comics/halfway-hotel/ Halfway Hotel]]'' is a hotel where the newly deceased hang out until they're ready to pass on to heaven or hell. The staff are a mix of angels and demons.
[[/folder]]

[[folder:Web Original]]
* The Sands of Time in ''StarHarborNights'' is an extradimensional tavern. Its existence has been used to justify at least one "incredibly pointless cameo" from a minor ''Literature/TalesOfMU'' character. It also shows up in the second "year" of ''Tales of MU'' as the inn of the black door, where Mack goes to find Pala and encounters Morgenstern from ''Star Harbor Nights''.
* Ouroboros a.k.a. The Pub in the Hub of the Multiverse, from ''AHDotComTheSeries''.
* GameFAQs has an invite only board called "Restaurant at the End of the Universe"
* "The Inn Between Realms" was a thread in the now defunct Amazon.com Science Fiction & Fantasy discussion board and [[http://forums.delphiforums.com/sfboard/start its user-created continuation at Delphi]] that grew spontaneously from casual chatting through roleplaying to collaborative storytelling. It was mostly set in the titular Inn which, of course, was an example of this trope. How exactly it existed "between realms" wasn't entirely clear, but one explanation was that it carried with it a small area of geography whose edges linked to random places on various worlds at different times, without visible transition lines. In any case, everyone bringing in their various original characters reflected the world-connecting nature of the location. The story [[Administrivia/ThereIsNoSuchThingAsNotability remained mostly an insider thing]], but as a handful of the collaborators are published authors (no big names... yet) and many others are prospective, the setting may crop up somewhere yet.
* This is the general idea behind "dressing room" [=RPGs=] on Livejournal - the only difference being that your stay there is usually a lot longer than in other examples of this trope. The benefit of this setting is that players can come and go as they please; when a player wants to stop playing, they can simply stop posting and other characters will simply treat the disappearance as the dressing room sending your character home.
** "Jam jar" Livejournal [=RPs=] tend to be a combination between this and a CityInABottle setting.
* Stan's Place in ImAMarvelAndImADC is this between the MarvelComics and DCComics universes, as well as the real world, indie comic distributers like Creator/DarkHorseComics (where ComicBook/{{Hellboy}} hails from), and probably many more.
* The eponymous House in ''The House Between'', which sits outside of the Universe.

* The fabled 23rd Mr Smoothy location in ''WesternAnimation/Ben10Omniverse'', which was intended to sell smoothies in every universe simultaneously, and instead takes Ben to the universe of Ben 23.
