Carnival Buffet at Rio gets 5-stars for when I used to eat here. The variety of food choices was really nice. However, let's be honest. When Steve Wynn built the Wynn and I tried his buffet... I've never been back. At Rio you would get snow crab legs, at the Wynn buffet you get king crab legs and they're sliced for you so you don't have to sit there for hours trying to take the shell apart. I haven't been here in awhile so it could have changed, but if Wynn buffet is still in the picture, I don't know if I'll ever come back.
