I've been to Jing Fong on Elizabeth Street many many times and I've always been pleased. Unlike many other Chinatown dim sum places, Jing Fong's waitstaff are friendly and helpful. The place is awesome: a really very huge room with lots of seating. At peak hours, it can get noisy but you can still converse comfortably without having to scream. The food, however, is the highlight. They have the plumpest and juciest shiu mei and har kow. They also have this yummy pan friend scallion dumpling. If anyone is looking for a really great place for Dim Sum, I definitely recommend going to Jing Fong for great dim sum and good service.
