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.
Camping in London? Absolutely! This is one of a few sites which has direct access to Epping Forest from the campsite. Easy to get to by tube, with a fire field and 50 acres to spread out in, this is a great place to recharge your batteries.
The second coffee shop has to be Kaffeine. Having only recently come across this one, I was certainly impressed and they may even have the best coffee I've had, since a short stay in Portland, Oregon.
