Just spent the weekend in Vegas and had the opportunity to try a few buffets. (note: they were all dinners)
Wynn - As the newest and flashiest of the Vegas buffets, the Wynn buffet was pricey but well worth a try. The dining area was divided into 6 main sections serving salad, seafood, shellfish, asian, grill, and dessert. There was a carving station offering prime rib, veal as well as a very tender and just a bit spicy rack of lamb. The quality of the meats were excellent (I particularly enjoyed the ribs), as was the salmon wrapped in puff pastry. As with most buffets, the variety of fish was overcooked and dry. The sushi was below average with a very limited selection and bland flavors. For some reason I'll never understand I had insisted on trying ALL the desserts which left my extremely full and satisfied, not to mention a bit sick. Sweets which stood out for me was the strawberry and rhubarb cobber with a crumbly buttery shortbread topping. Not too sweet, the dainty bits of flavorful rhubarb and strawberry paired satisfyingly with the butter rich shortbread. This was the only buffet that served their bread pudding (studded with walnuts, chocolate and dried fruits) with creme anglaise. The crepe station had a consistenly long line, though was nothing out of the ordinary. They had a wide selection of gelato ranging from bananas foster to hazenut and pistacio and well as the classic chocolate and vanilla. At one end of the station were plenty of cookies, cupcakes and madelines to pick from.
Bellagio - The carving station offered venison, lamb, primb rib as well as pork. However, this being my last buffet of the three I was tired of such lavish meats and opted to have some pizza. Much to my happiness the shrimp scampi with pesto and goat cheese pizzas were extremely satisfying with its delicately crisp crust and generous smother of pesto topped with mozzerella and decent quality shrimp. Breaking another buffet rule, I also filled up on bread here as I found it terribly difficult to resist the squares of fragrant sun dried tomato foacccia and soft and salty pretzel sticks. Bread pudding here was my favorite (even without the creme anglasise), not very sweet, served plain and the most custardy of the buffets. The passion coconut mango soup topped with a soft meringue was toothachingly sugary and tart, but the floating island in a small glass with a thick layer of caramel at the bottom was delicious. As for ice creams, the Bellagio only offered a do it yourself soft serve station with an assortment of toppings.
Mirage - Cheapest of the trio, I was a bit dissapointed by the quality and options avaliable at Cravings (Perhaps I was spoiled by Wynn and Bellagio). They did, however, have a couple of items that the other buffets didn't include such as a made to order salad bar and a surprisingly good souther food as well as a dim sum selection of har gao, char siu baos and siu mais. But as expected, the quality of the dim sum was not very authentic or even enjoyable its own right. I did like the cranberry brie and walnut pizza (but made the mistake of having 3 slices and being to full to eat much more). The creme brulee was just thick enough with a thick crackly sugar crust but served in one large 'scoop however much you want' tray as opposed to the single serving dishes at Wynn and Bellagio.
Overall? If I were to go back to one buffet it would definitely be the Wynn, although the Bellagio dining room is always full as opposed to the Wynn had some empty tables during peak dining hours. Service was decent, though waiters were often slow to take drink orders and clear dishes (esp. at Bellagio). All three offered a wide selection of sugar free desserts (but sugarfree never manages to taste as good as the real thing!)
