We went for dinner on New Year's Day 2012. I would rate it closer to a 3.5 than 4. My wife liked it more than me. For me it was quantity over quality. I would hasten to add that as far buffets go it was really good; as good or better than Bellagio's. On the downside, the crab legs had no taste whatsoever. They were split open for ease of eating and they were continually well stocked since this was a popular item. I tried the prime rib and it was very good, but dry without au jus. The sushi was just average. The salads were good. The sea bass was just average in my opinion. The shrimp was very good--firm and fresh. Cocktail sauce has some kick!
The wife got lamb and loved it, and lamb stew and said it was very good.
She also tried the spiced lentils and curried chicken.
Overall, the selection is excellent and the quality is high. I appreciate how difficult it is to serve high quality food on a buffet line. But there are so many people coming through that the turnover is high and the food should be fresh. I think we got our $80 worth ($40 each). But I ate too much and felt the consequences thereafter. Our resolution for 2012 is no more buffets!!
