Mai Pearl recently started serving dim sum on Sat & Sun (12-3). I was invited to an opening party last weekend and got to sample about 10-15 different items. The food was equally as good as China Pearl in Quincy, maybe even slightly better. For those of us in the suburbs, this it really a great - no need to go to Chinatown (or Quincy) to have excellent shrimp dumplings, pan-fried turnip cake with XO sauce, stuffed eggplant, clams with black bean sauce, and mochi filled with black sesame seed paste. These were some of my favorites. The dim sum menu is not on their website, but I've uploaded it here.
The Mai Pearl regular Chinese menu and sushi are excellent as well, but glad that they have added dim sum.
