As far as a buffet goes, Chinatown is one of the larger ones I've been to. As I recall they had 6 buffet bars, with maybe 40 things to choose from. They have your standard fare of various deep fried mystery meats, hidden in thick sauces to cover their low quality. Finally, as you'd expect, they have a large desert and ice cream bar.
Interestingly though, they had a whole section where you could make your own bowl of food and have them cook it for you. There were lots of veggies, meats, and various sauces to choose from. Simply put everything in a bowl and the staff tosses it onto a huge grill, similar to places like Mongolian BBQ. This might be your safest bet, as you know exactly what your eating.
I'll admit it, I'm not a huge buffet fan, so I'm a little biased. I give it 3 stars based on size alone.
