London

No longer the be-all and end-all of East End clubbing, this three-floor institution still draws queues for indie-rave mash-ups at the weekends. 333's basement bar was reputedly originally built as the lock-up for the town hall across the street. These days its dark and intense surroundings host a handful of decent nights with suitably ironic titles such as Shoreditch is Shit, We Have Fun Present We Have Hangovers and Last One In's a Rotten Egg. Upstairs is just like a house party, complete with broken loos and random strangers falling over you. 333 is no longer somewhere you plan to go, it's somewhere you end up.
