Actually 3.5 but I'll be nice. The buffet is very pricy at $37/pp dinner and really I did not see so much variety and no prepared to order items like the Pasta station at the Mirage at $31/pp and you can get tix 4 tonight discount there (I have no association with them). Anyway the prime rib was very nice and the desserts good. I honestly found nothing exceptional though I wish I would at Bellagio as I am always impressed with the property.
Also their servers bring you beverages which I know may be nice, but is not as flexible as other Vegas buffets that offer drink stations where you can experiment. I know my kids, on a previous Vegas visit, enjoyed the push button soda station at Cravings. Also I would not say their service was so prompt or their removal of empty plates.
