I'm off to London May 22-26 and one of the guide books recommends club XXL. It's close to my hotel and from the description looks like a good time. Does anyone have any experience with this club?

Also what does one wear clubbing in London? I ask because I got it sooo wrong in Paris a couple of years ago and felt like a monkey standing in club Queen. BTW I'm 45 and bearish (no facial hair) so I'm looking for advice on how I'd fit in at club XXL.
