Love this place! Delicious vegan iced coffees (possibly a bit pricey at 4.10E - I'm not sure about Madrid prices, but so good I had two), vegan frozen yoghurt, and great soya cappuccinos. It is nice and cool inside, and a relaxing place to hang out in, playing interesting music. You can see the owner put a lot of effort into it, and there is a lot of attention to detail - my capp was served in a small frying pan instead of a saucer! Right next to the metro, highly recommended.

Cons: Erratic/hard to establish opening hours
