Over-21s with money to spend on their wardrobes only inside this Old Town club, an indication perhaps that they take themselves rather seriously, which isn’t the case if you actually step inside. Not that there’s anything intrinsically wrong with Zero, it’s just a bit of a shame that they’ve opted for the classic disco formula complete with flashing lights and formulaic music. Frighteningly loud, the only reason to come here is to dance, or get laid.
