I agree with 5th ave, you normally have to try NOT to pull, quality is debatable at best though, unless you like a good slapper in which case it's probably heaven. Tell a bird you've just joined the army and you'll be out of there like a shot
I've never done 42s but I can't imagine it's as bad as I've been told
Just stay away from Piccadilly Gardens if you can, it's shit, very expensive, and full of proper knobheads, either rich knobheads with more money than sense, or poor knobheads on their annual night out. Kro is perhaps the worst of the lot, with very uncomfortable chairs, and an atmosphere like high school changing rooms but without the benefits of teenage clunge/cock to stare at out of the corner of your eye/through the crack in the door. (Is Piccadilly 21s still open and still a meat market?)
Printworks is full of teenage girls on stilts and teenage boys with raging hormones, it's OK, but a bit limited and very expensive, and the dress code used to be laughable, not sure it's as bad as that now, there are a couple of reasonably good clubs in there although I think Opus is still shut. Pretty sure all the bars have a 1am or 2am licence.
