I recently tried New China Pearl in Woburn for dim sum, and had the true Chinatown experience without having to deal with the Chinatown parking and crowds. The place was huge and they served all of the standard dishes including several types of dumplings, chicken feet, sticky rice, etc. Here's a sampling of my picks:
Beef Rice Noodles
Roast Pork Buns
Taro Stuffed with Pork
Steamed Shrimp Dumpling
New China Pearl was as good as most of my regular spots in Chinatown, and they served all of my favorites including, clams and black bean sauce, roasted duck and taro shrimp. Dim sum for four was around $70 and definitely ordered more than we could eat. If you live outside the city, this is more convenient than Chinatown and I would definitely go back.
