This is the largest buffet by Vegas standards. Lots of food but the quality is so-so. If you don't really care about the quality but just want a large variety try this one. Although there is seafood on the basic buffet if you want more of the better stuff be aware you will have to pay extra for it.

My wife and I visited the buffet at the Rio last week (April 3) for dinner. For $15 more you get rights to the seafood section which consists of clam chowder (not bad) marinated shrimp and regular cooked shrimp for cocktail. A variety of clams casino, oysters on the half-shell, etc. They didn't look appealing to me so I skipped... More

I read the mixed reviews on here and after eating at the Rio Carnival Buffet, the customers who said this buffet is terrible are correct. I upgraded to get the seafood items. I wanted the lobster tails. I know they are not Maine lobster tails, but there were awful. They were mushy and had no flavor. Also, I didn't know... More

The buffet is right off the casino without any dividing wall so the entire restaurant smells of smoke. The food is literally disgusting. Everything greasy,fried and lowest possible grade.I have found a hair in my food and that made me not even want to finish one plate. Wasted money and left hungry. Whoever says the desserts are good probably never... More

I was at their sea food buffet several times and always was very satisfied. This time I found the quality in general was mediocre, somehow not worth $ 38. Not sure if I will go back. Theres was enough food but it tasted kind of all the same, nothing special.

Huge selection and wonderful staff, easy to navigate just seemed though that some of the food was ok not great. I really didn't expect it as it's a Buffett but for stuffing your face this is the place

Always loved the seafood buffet at the Rio, but have to admit when they combined it with the World buffet; it isn't quite the same as it use to be. The World buffet is OK. You can buy discount vouchers at vendors on the Strip, so the cost is more reasonable.

I went here especially for the breakfast buffet. But after walking through the entire casino, it turned out to be closed permanently. A notice would have been nice!! I had to ask a security guard what was going on.

A bit expensive, but the seafood buffet was spectacular! Everything was very good, and we would definitely visit again!

I enjoyed the Rio Carnival Buffet. The variety, selection and quality of the food was good. I had broccoli, spinach salad, quinoa salad, squash, sweet potatoes, pineapple, watermelon, cantaloupe, honey sew melon, guacamole and trout. Everything tasted good. There were many other choices available. I paid for my meal using Total Rewards credits. The Total Rewards loyalty program is one... More
