This place serves dim sum (like their name states) but that doesn't mean they offer good dim sum. I think this place stays busy because of the lack of competition in the area for dim sum. I've had better, much better for the same price in a variety of places around the nation.
I think their dinner service is slightly better than the dim sum. If you want authentic Chinese food, you can pretty much order whatever you like here. The food is pretty average but if you have a craving for something special and unique (like your mom or grandmother made for you), you could give it a shot here.
