Great buffet, the seafood upgrade cost more but is worth it. Endless crab legs. The lobster are small but you can eat all you want.

Food was OK but not worth the price. Staff were very friendly, looked clean. Hours have been reduced so they don't offer breakfast. If you buy the one day pass, you have to travel to the Strip to eat breakfast.

The experience isn't the same since they combined the two Buffets in the same location...Now they stamp your hand so you can enter into the seafood portion of the buffet. The Seafood Buffet isn't as extensive as it use to be which is disappointing since it was always a highlight on our trips to Vegas. It was still good, but... More

We have been huge fans of the Rio Seafood Buffet for many years. We would go there twice each Vegas stay. This year was our first trying it now that they moved to the Carnival World location and made it an up charge. We were totally disappointed. We arrived right after opening at 3:00 pm on Sunday. The Seafood was... More

The food was dry and terrible. The food selections were poor in comparison to other buffets in town. To top it off, their service was non-existent! I wish I could have run away! It was one of my worst experiences ever!

This used to be better. Now at $35 and $20 additional for lobster pieces and a few additional things that should already be on the $35 menu it is not worth it.

Obvious why its the best seafood buffet in Vegas...especially for anyone who enjoys crab legs, little necks, oysters & numerous other hot & cold fish dishes ~ no wonder some people were carrying 3-4 plates at once.. The standard buffet offers American, Chinese, Japanese, Mexican, Italian ~ carving stations with prime rib, turkey & ham, scrumptious salad & fresh fruit... More

We had such high hopes for this buffet but after reading the reviews I was skeptical. I had been wanting to eat here for a year so we decided to give it a shot. It missed the mark. When we arrived for dinner at about 8, there was no one in line so we got in easy. The waitress was... More

The buffet at the Rio, so famous for its seafood, is seriously overrated and over priced. Be prepared for a $20 up charge if you want the seafood included (appx $53). The regular buffet has very little unbreaded (grilled) foods - heavy on Asian. The carving station was nice although I only tried the turkey. The dessert station had great... More

We've had better buffets, especially at the price they were charging. Our complaint was that we felt like there should have been a better selection when it came to certain categories of international and nation wide flavors.
