Originally known as the "Barista AU", this form of fanwork began life on Livejournal but has since become popular across the board in fandoms. It is especially popular on fanwork sites such as Archive of Our Own and Tumblr.
The origin of this AU is uncertain but it seems to have first popped up within the NSync and Backstreet Boys Real-Person Fic community in 2001. It spread amongst Stargate Atlantis fans, and ultimately other fandoms took note. The AU became especially prevalent starting in the early 2010s.
Coffee shops are known for a comfortable, casual urban feel that lend themselves well to all sorts of shenanigans. The default in this AU is that it's a shipping fic where one half of the pairing is a barista and the other half is a customer. This type of AU is popular due to it being a form of Meet Cute. Another popular form is for the coffee shop to be a Local Hangout where most of the cast either visit or work at. The third most common form is where both characters are baristas who work together. If a character loves coffee, then expect a lot of coffee shop AUs involving them.
The "Coffee Shop AU" is often seen as a counterpart to the High School A.U.. Due to writers drawing from life, teenagers will favor high school stories while young adults like coffee shop works. As a similar result, this AU often overlaps with the College AU fanwork. The characters either work at the coffee shop to help get through college or college students tend to frequent the coffee shop.

- Amongst the bandom, Panic! at the Disco and My Chemical Romance fans are especially prone to this sort of AU. Panic! At The Disco's Jon Walker once worked as a barista prior to joining the band. My Chemical Romance fans know of Gerald Way's love of coffee, and thus he frequents coffee shops a lot in fanfics.

- Steven Universe:
Lapis: So what does happen in Empire City?Steven: Well, if you moved here you could get a cool apartment and be a single Gem taking on the big city. You'd have a fun job at a local coffee shop and come home to a wacky roommate...Lapis: I have no idea what you're talking about.
- The show itself pokes fun of this. In "Same Old World", while flying over Empire City (their world's version of New York City) with Lapis, Steven mentions that she could move there and work at a coffee shop:
