I would without doubt recommend Ping Pong - the concept is great, it is such fun with a group of friend to order many of the available dishes and share between you. I did exactly this last Sunday with a group of 10 of us, the service was great and the food and cocktails were flowing. I am so bored of pizza and pasta and Dim Sum is much lighter and healthier than going for your normal full-on Chinese. I will definitely be going again soon - in fact may go for some cocktails tonight?!
