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.
Aside from the fact of the underground being the oldest running railway system in the world, I find the underground just an incredibly strange place. Sometimes it’s like I’ve entered an organised maze and just walk without even thinking. The photo is taken of the floor from one of the trains, it’s normally what you tend you look at when you’re on the train.
Great comic shop that stocks small press, and everything else you'd expect to find. The kids section starts at early ages and has something all the way up.
