TS releases do have good audio. Cams in general have a lot of visual problems though; poor color accuracy, warping, incomplete frames, sometimes people moving around, things like that. Also pretty much every cam I’ve seen lately has been covered in ads for sketchy gambling sites throughout the entire runtime. None of this makes for a good viewing experience.
Also, I don’t think I’ve ever seen a cam with subtitles available.
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. https://memory-alpha.fandom.com/wiki/Restaurant
