I've not been impressed by Manchester for a while now, not just the prices, just the general 'meh' feeling I get when I'm there, and the lack of quality that the bars actually provide.
Post Fulham game, went to some bar in Ancoats, where me and my mate got a pint of Estrella, which came in a plastic pot, and we were charged north of £7 each a pint, plus a service charge of 10%.
Back to the OP, 20 stories is alright, if you're not getting in the way of pretty much every other person wanting to take a picture of the gaff!
As for Northern Quarter, used to like it around there but not every bar is pretty much the same, and the chances of you getting your beer in the glass it was meant to be served in, are less than zero!
