The tunnels are a Crane.tv favourite. We have used the space as a backdrop for several films including a music session with The Civil Wars. The tunnels have a great story behind them and feature one of the only legal graffiti walls in London on their Leake Street side which was championed by Banksy back in 2008.
Brilliant Corners...Great sound system, vinyl only, dancing, left field, fourth world, jazz, afro, and some refreshing cocktails to help with all the sweating. Probably the only place i will actually dance in.
They also do amazing Japanese food earlier in the evening.
Everyone who works at Daunt Books seems to have the answer to any question you might have, watching my large dog carefully navigate their narrow aisles is always fun too.
