Trust me, you don't want to go there. I've only ever walked past it going to other bars in Vauxhall. If you like anonymous bareback sex, drugs and the aroma of poppers/ shit then this is the place for you!
A friend of mine knows a paramedic who was called there once after someone overdosed. This guy was lying on the floor unconscious wearing just his leather being treated by the ambulance crew with all these other guys standing around with their hard ons hanging out. Nice.
