I too can't believe that TimeOut rated it 3 stars! I just returned from London from a 2 week vacation and had to stick to a gluten-free / milk-free diet, and finding places that cater to those dietary restrictions is difficult. Most restaurants in London did an okay job at having gluten-free / milk-free options but this place by far served one of the most tasty meals during my two weeks. I had the Pollo alla Romana and the Rocket with fennel, green beans, oranges and olives, and topped it off with a brownie. They also had a lot of vegan options. The owners very friendly and welcoming and the atmosphere was bright and comfortable. Having been spoiled by New York City and San Francisco cuisine, this measured right up to what you would find in either of those cities. Again, not so of a lot of places I ate in London, living up to the American stereotype that British food is often not very good and completely over-priced.
Also, Time Out has them listed under Chinatown area but it's really much closer to Covent Garden and Soho, one block from Shaftesbury Avenue.
