I been a Rio's buffet fanatic for years, and this time I decided I would listen to the yelpers and went for it , and It's EXQUISITE!!! the place is far if you get in from the east wing,(aria shopping center) I recommend on your first visit and if you are not staying at the Cosmopolitan to go through the main lobby, it's a lot closer, but moving on to what it was amazing, the food is like a dream come true, small portions of everything, for some people this might be inconvenient, for me it was perfect, they have a seafood bar with a chef on the spot making butter shrimp and those were yummy!!!! I got there an hour before closing but the girl at the front warned me before I paid. But I was there already and an hour sounded enough to try all their menu, and I did get to tried everything, kind of have to rushed at the end for the dessert, but it was my fault for getting there late... not to late they closed really early, for been a buffet on Vegas I wish they would stay open for at least an hour more.
Definitely will bring back the family to this place next time i'm in Vegas, this was a business trip
