Hard to know. You could argue that Hooker or Or or whatever should in theory never survive in somewhere like B&C where there's a rotating cask, oodles of bottles of new stuff, and frequent guest beers for folks to always try new stuff, but that clearly doesn't seem to be the case.
I know that when I go there I rarely drink the same beer twice in a night, but rather flit between many, whereas when I go to a crap pub I will drink my lowest common denominator (guinness) all night. When I go somewhere that has Hooker but not much else, I'll drink that all night.
