It is an independent arts organisation in Elephant and Castle. It is one of the best venue for electronic music in London. On Tuesdays Boiler Room, best DJs for free with guest list.
There are not many places in London like it. On a Saturday during market hours it heaves with stalls and visitors for a good mile or two. Great place to pick up some bric-a-brac, genuine oddities and a great bite to eat, or just enjoy the hustle and bustle vibe of the place.
