Accessed via a tiny and difficult to find door in London Bridge tube station, the Shunt Vaults has a good claim to being the most inaccessible and spooky bar in London. Once you find the entrance, you plunge down a long unlit corridor, which is in fact a real life London Underground excavation, complete with blind alleys leading off it and spine chilling dripping sounds.

Once accessed, the bar is like a cave – albeit a welcoming one. Shunt specialises in interactive theatre and the weirdest end of the cabaret spectrum. You won't be allowed to enjoy your drinks in peace, but an exhilarating spectacle of some sort will unfold and possibly involve your table.

Shunt has a claim to being one of the best fringe theatres in London, although performances are by no means regular. This was among the first spots in London to pioneer the ambulatory 'theatre in the round' which mixes in performers with the rest of the action and the crowd.

At weekends, their parties continue long into the morning and revelers are able to wander at will into the rear arches of the vaults, where you are just as likely to find a pirate ship full of luminescent people dancing to hard techno, as a full costume English tea party.

A truly unique and sometimes scary place, Shunt is not everyone's cup of tea but it will certainly stick in the mind for years to come.
