Writing as somebody who *did* make it past this club's ludicrously subjective make-it-up-as-you-go-along door 'policy', I can confirm that your best efforts are rewarded by a venue with much more hype going for it than substance. Does 'anything go'? Of course it doesn't. The most risqué this place gets is equivalent to an edgy burlesque performance. There are occasional 'acts' on stage which are curious to enjoy, but anything but erotic. Anyone who thinks this equates to hedonism needs a good night out at a proper club where pumping music and rhythm whip the crowd into a throbbing mass. The Box is just a bunch of wealthy people (plus tragic wannabes) engaged in an overpriced circle jerk of mutual congratulation.
Save yourself the bother, don't believe the hype, and see to your 'needs' before leaving the house. Then get down with your bad self at any of London's superior, louder and more tolerant and accepting venues. There are some amazing places to enjoy but unless you're fixated by the need to be seen somewhere (even if it means a crappy night out) then The Box simply ain't it.
