Food = good.
Desserts = blech.
They don't have a lot of selection like the bigger buffets at other hotels like Rio or Bellagio. It'll be good to go maybe once or twice during your trip. Our deal was free all day passes with our hotel reservation. So we ate at the buffet 4 times and were all buffet-ed out after that.
The service was awesome although they need to organize themselves a bit to make the lines go faster when you pay.
The selection of food might have been small but everything was well made. Crab legs were awesome as well as the braised oxtail, stuffed pasta shells, beef tamales, posole...etc. etc. The only food that tasted bad was the sushi because it was cold like pre-made market sushi.
Tried the desserts and have to say that nothing was worth getting seconds for...except for the chocolate chip cookies.
