I'm really surprised the Bellagio buffet currently ranks higher than the Aria buffet on Yelp. For the same price the Aria buffet is without-a-doubt better. All four people in my group unanimously agreed on that.
Everything here felt underwhelming. I realize Bellagio was Vegas's original super-luxury hotel, but it's beginning to show its age. The space itself looks worn and out-of-date. There's not a good flow between the stations so people are constantly bumping into each other. The food itself is OK but not great. I'd definitely opt for Aria again if I had the choice between the two.
