China Pearl in Quincy has something that no other Chinese restaurant in Boston has: A PARKING LOT. It also has copious amounts of bubble tea in Kam Man supermarket next door… which I almost always go to right before a wedding banquet here. :) Decent food. Easy access from the city. Spacious dance floor and a stage area for the two main tables.
Note: If you don’t fill up the entire space (500 people or so), they’ll divide up the room and still serve their other customers.
