4 of 4 visits to their dim sum setting had problems; 1. Cold and poor tasting food 2. No problems, but nasty staff 3. 20 minute wait for item that never appeared 4. Stone cold shrimp dumplings. Many people near Quincy go here since the distance is shorter than the Chinatown places; but, in my opinion, it is better to travel than tolerate this problematic situation. Also, the Kam Man center has a few other restaurants of much higher quality.
