There is a jumja kiosk on the DS9 promenade. It also had a bunch of different restaurants. Klingon and Bajoran are the two i remember off the top of my head.
I seem to remember a scene in Babylon 5 where Vir got sick eating at a place that sounded like a rebranded McDonalds. Londo was chastising him saying you know Centauri stomachs can’t handle fast food. I wish I had time to rewatch that show.
That one is difficult because in star trek they had replicators that could make any food instantly. I've never actually watch B5, so can't speak on that, but at least in the star trek universe, fast food would be pointless unless it was in the Delta or Gamma quadrants because it was never spoken about with the residents there. Good question though
Voyager mentioned several times that replicator technology was not widely known in the Delta quadrant. They had Neelix cooking slow food to save on replicator energy usage. There were plot points of possible technology trade with the Kazon and others.
Star Trek still has traditionalists and hobbyists that prepare food without replicators. Sisko's father famously ran a Cajun restaurant in New Orleans. I wouldn't be surprised if someone ran a fast food burger shop because "the fries just don't crunch the same from a replicator" or something.
It also would be possible to have something like a replicator kiosk shop, which would be like fast food.
There are a few restaurants mentioned on the wiki, but they don't distinguish between traditional preparation and replicator food (it includes Quark's on the list). None of the space ones look like fast food though.

Came here to say this. Expanse hits the notes of "real people actually live on this ship/station" way more than any other sci-fi I've consumed. Fast food, bars, brothels, restrooms, storage and maintenance areas, all of these are specifically called out at most stations.
I noticed this too, The Expanse does that so well, really fleshing out what life would be like living as a grunt in The Belt. They had their own culture, their own sayings, their own food. Like any colony, it gave host to any number of establishments meant to provide a bit of comfort out in the inky black nothing. The shared suffering also gave them a sense of community, which is a powerful motivator when the far off motherland starts imposing increasingly burdensome levies... Makes you want to grab the closest thing and hurl it at them! 😉
Wall-E had people ordering liquid fast food on their iPads and having it immediately delivered by drone. So fast food on a space station, but not a conventional restaurant experience i guess.
As someone who hasn't really watched the show, I see all sorts of things and just accept it. My brain can not handle it having a society with no money. Capitalism has ruined me
In Outer Worlds there's a couple establishments aboard the groundbreaker that could potentially count as fast food by some definition.
The stand on the citadel in mass effect is maybe fast food-ish
I vaguely remember seeing some stands in the background of Babylon 5 that could potentially have been something like fast food, but I never got into Babylon 5 too much so I can't say much about that, I just have some vague memories of some parts I've seen that looked like fast food wouldn't be out of place.
Pretty much any time there's a big space station with a city-like interior I assume there's probably something like fast food somewhere on board, maybe even visible in the background somewhere, though I can't really think of any particular examples or any time it was specifically highlighted
It's five-star, not fast food, but there's Milliways, the Restaurant at the End of the Universe, which serves a delicious Pan Galactic Gargle Blaster. Don't let the five-stars scare you off:
All you have to do is deposit one penny in a savings account in your own era, and when you arrive at the End of Time the operation of compound interest means that the fabulous cost of your meal has been paid for. (Many claim that this is not merely impossible, but clearly insane.)
This is why the advertising executives of the star system of Bastablon came up with this slogan: "If you've done six impossible things this morning, why not round it off with breakfast at Milliways, the Restaurant at the End of the Universe."
SS13 has a chef on the station who makes all sorts of food, but mostly pizzas and burgers. I don't recommend eating their food though, it's pretty likely it will be made of your coworkers.
