I am not actually certain what time this place closes. I was there on Friday night; we left around half past one, staggering a little, and the place was still full and still serving.
Quinn's is on the Kentish Town side of Camden, a little removed from the markets and the tourist traps, so the crowd isn't generally aggressively subculture and it's not as hideously expensive as one might fear; well, unless you're drinking one of the truly immense selection of imported European beers. I am not kidding when I say they have a staggeringly comprehensive selection of Belgian beers, as well as more than a few from other countries. They also have a decent range of real ales on tap - on numerous taps, all the way down the bar. Oh yes, the bar. It's bigger than some pubs I've been in, so even when the place is full getting to it isn't that much of a struggle.
There are a couple of flat-screen TV's in there, generally showing sport ((of the rugby and cricket rather than football flavours)), but tucked away muted in corners so they don't intrude. The decor is pretty modern, it's wallpaper and red upholstered benches rather than wood panelling and horse-brasses, given a sort of twenties class by elegant lamps and stained-glass signs behind the bar.
Even on Friday night it doesn't get cruelly overcrowded, due to its size, and during the day it's empty enough to be a nice quiet place to retreat to with a book and a pint. You won't be made to feel unwelcome for drinking slowly, either. Quinn's is great and I urge you to pay it a visit if ever you find yourself in the area.
