Food was a disappointment... This is our second visit to Yauatcha. The first was very good (around 3 months ago), but the second (Feb 4th 2011) was a major disappointment:
FOOD: The food was only bearly above the level of quality expected from a Chinatown restaurant, which given the price premium, is unacceptable. The starters arrived after the main course - Shanghai dumplings (which had to be sent back as there was a hair embedded in one of the dumplings) and Spicy soft shell crab (which was limp, hidden among a lot of dried fodder and is still repeating on me). The mains were tasty, but nothing special - the twice cooked pork belly with chilli had lots of flavour, but the pork was very thin, over-cooked, and therefore dry; The rib eye beef with black bean sauce wasaverage, and the french beans with dried shrimp have been cooked with more flavour in my own kitchen.
DRINKS: The cocktails turned up 20 mins later with the main meal, which meant we had three different drinks in front of us. Both cocktails were hastily prepared (despite being late), and not overly exciting. Sake and beer was good.
SERVICE: The service was refreshingly friendly (which seemed to vary widely depending on which waiter you got), although the knowledge of food was average, and the speed of service was very slow (in fairness it was a Friday night and Chinese New Year, only an excuse in London seemingly).

Overall, it is unlikely I will return here which is unfortunate, as the concept of a trendy, up-market and contempory dim sum / cantonese is a good one.
