If I were younger and still had the fortitude to make Bellagio regret charging so little for the amount I was able to consume this might have been a five-starer. As it is, I think it's one of the better buffets in Vegas. There's plenty of diverse foods (see Ostrich) that peaked my interest and I enjoyed the experience.
Unfortunately at this point in my eating stage, the buffet experience doesn't cut a dedicated restaurant or chef.
