'''''The Restaurant at the End of the Universe''''' is the second book in the [[TrilogyCreep increasingly inaccurately-named]] ''Literature/TheHitchhikersGuideToTheGalaxy'' trilogy. It constitutes the second half of author DouglasAdams' original radio story; due taking a legendarily long time to finish his manuscripts, he couldn't fit the whole thing into one book and his publishers told him to just give them what he had and that they'd publish the rest separately later. Those familiar with the [[Radio/TheHitchhikersGuideToTheGalaxy radio series]] knew what to expect here before ''Literature/LifeTheUniverseAndEverything'' took them to wholly new pastures.

Following directly after the events of ''Literature/TheHitchhikersGuideToTheGalaxy1'', ''The Restaurant at the End of the Universe'' finds our motley crew (hapless Englishman Arthur Dent, his alien friend Ford Prefect, human female Trillian, Galactic President Zaphod Beeblebrox, and Marvin the paranoid android) under attack from the Vogons, this franchise's brand of bureaucratic-minded green-skinned space invaders, after the destruction of the Earth. They manage to escape with some supernatural help, and Zaphod gets caught up in the conspiracy that compelled him to become President and steal the starship ''Heart of Gold'' in the first place (which he erased his own memory about for security reasons, and has no desire to get back). After finally finding out from fellow conspirator Zarniwoop that their objective is to meet the person who actually rules the universe, he decides not to go along with it and escapes.

Instead, our heroes go out to lunch at "the nearest place to eat" -- which turns out to be the luxurious Milliways, the title restaurant, where diners can enjoy witnessing the destruction of all creation while being treated by [[LetsMeetTheMeat food that literally begs to be eaten]] and entertained by the stylings of stand-up comedian Max Quordlepleen. Following an incident involving a dead rock star's high-class stunt spaceship and a rather large sun, Arthur and Ford end up teleported onto a massive space ark full of telephone sanitation engineers (among other middlebrow professions) two million years into the past... while Zaphod and Trillian end up right back where they started.

In the end, Zarniwoop drags Zaphod and Trillian along with him to meet the man who rules the universe... and gets an unpleasant shock. Arthur and Ford find themselves stranded on a prehistoric Earth, where the true and shocking origins of the human species -- and the final outcome of the program to find the Ultimate Question -- are gradually revealed to them.

!!''The Restaurant at the End of the Universe'' provides examples of the following tropes:

* BathsAreFun: The captain of the B Ark spends most if not all of the voyage in a bathtub in the center of the ship's bridge and endorses the idea that "You're never alone with a rubber duck."
* BegoneBribe: There's a violinist in Milliways who Zaphod and Ford get rid of like this. He leaves and goes over to bother Arthur and Trillian.
* BogglesTheMind: {{Invoked|Trope}} by Arthur, when he pulls out Scrabble tiles at random in an attempt to reveal the Ultimate Question from his subconscious, and reveals "[[spoiler:WHATDOYOUGETIFYOUMULTIPLYSIXBYNINE]]".
* ConditionedToAcceptHorror: The sentient food at the title restaurant was specifically bred to want to be eaten.
* CoolStarship: The Milliways' parking lot is ''packed'' with them. Naturally, our heroes pick the one that's got a date with a ''[[HurlItIntoTheSun solar flare]]''...
* EpicFail: Arthur's attempt to get the drink replicator to make a decent cup of tea causes the ship to shut itself down just to figure it out, nearly getting the crew killed.
* HoistByTheirOwnPetard: All the ''useful'' citizens of Golgafrincham relieve their planet of excess population by tricking all their planet's [[AcceptableTarget middle-managers, telephone sanitizers, advertising executives]] and so forth into believing that a nasty (if ill-defined) apocalypse is threatening their world, packing them all onto an enormous ark, and shooting them off to crash-land on some InsignificantLittleBluePlanet. After which they get on with rich, fulfilling lives until they are all killed by a nasty disease contracted from a dirty telephone.
* HurlItIntoTheSun: The fate our motley crew is threatened with after space-jacking Desiato's ship.
* ItsAllAboutMe: The Total Perspective Vortex confirms Zaphod's narcissism... because he's inside a virtual universe that does, in fact, center around him.
* LetsMeetTheMeat: TropeNamer. A genetically-engineered bovine alien at the title restaurant offers itself as food for Milliways's patrons.
* LiteralMinded: Eddie, the ship's computer for the ''Heart of Gold''. Zaphod asks for it to send them to the nearest place to eat -- so it sends them to Milliways, the Restaurant at the End of the Universe, which is on the same planet (Frogstar World B) but 576,000,000,000 years into the future.
* MeanwhileInTheFuture: In the last part of the novel, the scenes with Arthur & Ford are intercut with those with Zaphod & Trillian, despite being two million years apart.
* MistakenForAfterlife: The crew of ''Heart of Gold'' right after their sudden transportation to the restaurant.
* NorseMythology: A group of small Asgardian deities dines at Milliways, marking the start of the Adams-verse's flirtation with ancient Scandinavia.
* OnlyMostlyDead: Hotblack Desiato
* ThePhilosopherKing: The Ruler of the Universe, who has utterly embraced Solipsism.
--> '''Zarniwoop:''' But don't you realize that what you decide here affects the fate of trillions of people?
--> '''Man in Shack:''' I don't know them. I've never met them, and neither I suspect have you. They only exist in words I ''think'' I hear.
* PlanningWithProps: Played with. Ford's drunken explanation in Milliways.
* PutOffTheirFood: During the dinner at Milliways, Arthur initially orders a steak, changes to a salad when he finds out what the steak comes from, and eventually settles for a glass of water.
* SecondComing: The Great Prophet Zarquon makes his long-awaited return. Just as he begins to apologize for his tardiness, the Universe ends.
* ShapedLikeItself:
-->''"What," said Trillian in a small quiet voice, "does 'sundive' mean?"\\
"It means," said Marvin, "that the ship is going to dive into the sun. Sun. Dive. It's very simple to understand."''
* SleeperStarship: The B Ark, with a small awake crew.
* TheSlowPath: Marvin, who parks cars on Frogstar B for 567,000,000,000 years.
* SpotOfTea: Most of the trouble in the story starts when Arthur's attempts to get the drink machine on the ''Heart of Gold'' to make him a cup of real tea end up confusing the shipboard computer to the point of non-fuctioning.
* SuddenlySober: There's a cubicle-like machine outside the restaurant where you can sober someone up by sticking a coin into a slot. It's implied that such machines are pretty common, since Zaphod immediately recognizes it and knows how to use it.
* VengefulVendingMachine: Arthur Dent, sick of getting bad tea from the Nutri-Matic machine, gives it a lengthy lecture on the nature and history of good tea. The machine hijacks the starship's entire computing power to work on the problem, leaving the ship defenceless against a Vogon attack. Arthur gets his tea in the end, though.
