Deceptively large venue in the heart of Edinburgh, the place is a maze of rooms and passages the first time you go.  It's also incredibly hot on the main stage!  You can't fault the punters for enthusiasm tho - even when they're just through the door they're dancing and getting into the music.

If you're lucky enough to catch the club night a couple of doors down, you should definitely go - it's all set in stone cellars, giving it a wicked mediaeval/industrial atmosphere.  Plus the drinks are totally cheap!
