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.

Overpriced mediocre buffet. Cold dishes, most brought from the back vs. cooking it up at each station as they did when it was the best. No lines & maybe a few dozen diners at lunch, so the word is out already! Visited this casino & buffet dozens of times over the decades, extremely disappointed and saddened!

We have been to the Carnival World buffet several times and even when they moved the Seafood buffet to the location. We paid for the seafood buffet add on and it was $109 for two. The food at the seafood buffet was old, dry and did not taste good at all. The snow crab legs that were cooked seemed to... More

My friend and I were at the Rio to check particulars for the Penn & Teller show he would be attending in the evening. We were hungry and the hotel is at a fair distance from other options, so we went here (he was attracted most by the large sign at the entrance that reads ''Seafood Buffet). When I paid... More
