Ate here yesterday, and although some of you will know it (it has been documented elsewhere in GF blogs etc) but I just wanted to sing their praises.
It's a small cafe style place with a little outside seating. More to the point though the flat bread pizzas were delicious. They were SO good I had to check with their staff that I had actually gotten a GF pizza (they do non GF too) as although thin was still quite doughy. Quite reasonable too for a central London. One to commit to memory, along with my other favourite Honest Burger.
