The Mardi Gras show is gone? Too bad! Rooms are mini suites. I liked the seafood buffet, the lobster is a small slipper lobster tail. I think it has a great casino vibe, but it doesn't have good video poker pay tables. It does have a lot of food and drink choices. The gift show is about average. Seem to keep some interesting shows also.
I haven't actually stayed here, so I can't write anything about the hotel itself, but there are several reasons that I visit here.The Free Show in the Sky, the Seafood Buffet, the Big casino, friendly table game dealers and of course the WSOP all come to mind. Not far from the Strip, catch the free shuttle bus at Harrah's. Lets not forget the Penn and Teller Show!
Food at the Rio Suites Buffet is outstanding. The freshness and variety of food, is unbelievable. The variety of choices at the Mongolian B-B-Q outstanding. The waiter/waitress is unbeatable.
The first time I visited Rio, my wife and I tried the buffet that everyone raves about. It's decent, but overrated in my opinion.
The free Mardi Gras show is a must see.
Rio now has a Whopper Bar Burger King restaurant which is pretty cool if you like BK. You can get a Whopper with a ton of toppings that you don't see at your run of the mill Burger King back home.
My daughter, her two sons and I stayed at the Rio for two nights (comped) The room was wonderful, large and with a great view. The food was OK. The gambling wasn't very good, tho. Lost a lot.
