The Bacchanal Buffet is one of the best buffets on the strip, but it is also pricey. They offer a TON of variety of different kinds of foods. They offer crab legs and wagyu, which were honestly OK compared to some of the other dishes.
They also have a different menu for breakfast and I believe it is also a little bit cheaper. If you are lucky, you might find a Groupon with the Bacchanal and definitely get your money's worth.
Dessert is pretty bomb here. They also offer gelato.
