We go to Hong Kong several times a year and love good dim sum from the rolling carts every morning. It always tastes better (and is more fun) than ordering from a menu. We usually stay in Tsim Sha Tsui, but have to go farther & farther to find good dim sum from carts in big restaurants; lately we've enjoyed the London Restaurant on Nathan Road in Mong Kok. The servers are friendly, there's always a nice buzz and the food is great. We love the tripe, chicken feet, various dumplings, etc. Any suggestions will be appreciated. Thank you.
