I haven't been to the buffet at the Bellagio since 2000. I have many fond memories of eating there 14+ years ago and thought it was time to go back. What a mistake.
Most of the food is low quality. None of the prep staff in the kitchen knew of the specific ingredients in any of the food (I have a few intolerances... corn, soy, etc.), and many of them couldn't even speak English so I had a hard time figuring out what I could eat. This has never been an issue at places like Aria Buffet, Bacchanal Buffet, or Paris Buffet (all of which are exponentially better than the Bellagio).
I was so disappointed. This is the first time leaving a buffet hungry because I just couldn't risk eating food that I couldn't get ingredient info on.
