I would have rated it 5 if I had elicited a smile from the staff. Food is well made and extremely tasty. Last week was my third visit and the food is consistently of a very high standard. I would say the best in Chinatown, which is actually not hard. I had hot & sour soup, crispy lamb, and duck stuffed with prawn. Perfect. Prices are pretty mid range. Bottle of Pink £17.
