I went to it a couple of years back. The prices are in the $12 to $20 range for each item. Everything is sold separate which can add up quite a bit. For example, the main entree would be around $14.XX and the rice would be like $8.XX, the bread(nan) would be around $3.XX now multiply that by the number in your party. It was quite expensive. We went in the evening though. You can easily spend $100 for 3 people.
I hear they have a luncheon buffett but I do not know if those certificates are valid for lunch.
