This buffet goes head to head with the Wynn's buffet for the best in Vegas. I pick the Bellagio over the Wynn every single time and I'll tell you why-- THE WAIT IS SHORTER.
Honestly, when it gets to the fancy $40 per person buffets, the food is pretty much the same. You get all the gourmet meats, all the gourmet desserts, and excellent service. To get anything else would be business suicide especially when you're catering to supposedly rich clientale.
The difference is the wait. The Bellagio used to be excruciating before the Wynn opened but it's manageable unless you come 7pm on the dot. Then I will laugh at you. That's like coming to the DMV after everyone's off work.
There is something for everyone at this buffet and it's good breakfast, lunch, and dinner.
One cute trick my brother figured out is if you come in towards the end of lunch and pay the lunch price, they will switch to dinner with the dinner foods. Thus, you can get dinner for the price of lunch. I'm not sure if they close down the buffet during this period, it's been a few months since I last visited.
