If Heaven had a Chinese buffet, Bast would be it. I've never seen so much good food in my life. I especially like the sushi bar. It's not one those buffets where you can "try a little bit of everything" - there's too much food to do so!
However, since the restaurant is so popular, the food doesn't lay there like many Chinese buffets. It's always freshly prepared. Make reservations on the weekends and dinner time, otherwise you'll have a hard time getting in.
