I think one of the best chinese resturants in Boston is Heli La Moon at 88 Beach Street. It is in the leather distric opposite the Chinatown Gate. Try the double lobster, seafood bird nest and pork chops. Ask for Hon and he will make suggestions for you. Always a good sign is that 95% of the dinners are chinese. They have dim sum on weekends but it tend sto get very crowered so get there befot 11:00. Many people recomend peach farm in chinatown. I have found the food hear to be as good and it is a relaxing place to eat as peach farm is very noisey.
