We live in the area and have been to this location for both dinner and lunch.
The location is nice and the decor is beautiful. It gets quite busy at dinner time and much much slower during lunch service.
The dinner has always been good. Hot food and great service. The prices are similar to those at Mandarin. The lunch service on the other hand was terrible. As we were at the buffet selecting items we saw them microwaving food behind the grill and then bringing it out and putting it at the buffet! I mean I'm sure other buffets may use a microwave but I'm sure it's done in the back and not in plane sight for the customers to see!
I prefer the sister location dragon legend over this place. However neither buffets are that impressive IMO.
