I've had The Buffet at the Bellagio for weekend brunch (excellent) and weekday breakfast (okay) before. Finally, I tried it for the weekday dinner ($29.95 plus tax & tip). Overall, it was a highly enjoyable experience. There is a lot of variety (meat, fish, pizzas, pasta, fresh fruit, desserts), but not everything is equally good.
Some Highlights:
-The prime rib: flavorful and juicy
-The sirloin: kinda bland, a little dry
-The roasted turkey: unusually moist
-The pesto mashed potatoes: yummy
-The various roasted veggies: passable
-The mini-desserts: varied, I recommend the lemon meringues, the financiers, and the cappuccino mousse. The tiramisu was not good. The creme brulee was okay.
My husband liked:
-The bluenose: tender and well-complemented by the sauce
-The smoked trout: tasty
-The spicy hunan chicken: excellent
-Homemade chorizo: Spicy, strong, and tender, though a little dry.
-Among the side dishes, the paella and succotash had particularly rich flavor.
The Service: No problems here. Our ice teas were frequently refilled and our empty plates taken away.
