I always make sure to come here for their Sunday brunch buffet when I'm in Vegas. They offer so many choices, it's really hard to decide on what to eat. They make the yummiest omelettes (lots of different ingredients to choose from including crab and shrimp - mMM...). I also like that their shrimps are really fresh and huge as well. Their crab legs are already halved so all it makes eating them super easy. Their sushi is pretty good as well and they make a mean spicy tuna hand roll. The quality of their food definitely beats all the other buffets I've been too (including the Wynn buffet).
Best part about the Bellagio buffet? Their desserts of course! They offer so many decadent treats...there's bound to be something for everyone ;)
Only bad part is that the wait is usually 1.5 hours but it's so worth it when you're finally in there surrounded by all the yummy foods they have to offer. Definitely recommended!
