My husband and I came to the buffet before the Penn & Teller show. The up charge for the seafood portion was ok - not worth the entire $$ deserts on the other hand - amazing! Also can't beat the $13 ad on for all you can drink wine and draft beer

We had been here about a year ago and enjoyed it. It was terrible this time. Everything was cold that was supposed to be hot. The melted butter was so luke warm, it was cold by the time I got to my table to sit down. I wanted to have some Lobster Bisque, but there were zero chunks of lobster... More

We got a great deal on the buffet with a coupon, so we decided to pay extra for the seafood. It was not worth it. There was plenty of food in the other counters with seafood mixed in. The separate seafood counter was not worth the extra money. Just pay the regular price for the regular buffet.

Paid extra $20 for the seafood buffet and teeny tiny crab legs that weren't even split in half! There are far better buffets like the one at Mirage that at least split the legs in half for easier enjoyment eating! The dessert was good at this buffet but everything else (like the rest of the Rio property) is average, nothing... More

The outrageous $57 cost for this seafood buffet would lead you to think that it was going to be something really special... well think again. Save your money and go somewhere else. I was extremely disappointed and felt taken advantage of.

This buffet had a great selection! I was surprised that the Asian section had more intricate dishes, beyond the stuff they can make quick and cheap. Great buffet for kids too! They had a lot to choose from and the desert section quickly became their biggest priority (after their vegetables!) We usually go to the Feast buffet at a couple... More

I was here for the Star Trek convention and stopped in during a break to have lunch.  This is a large buffet.  On the day I visited, there was an Asian section and a seafood section with crab legs and shrimp.  Additional offerings included pizza, lasagna, a cutting station, vegetables and sushi.  The seafood was delicious and the pizza was...

Loved the selection of seafood at the buffet. Everything was not only cooked but seasoned perfectly. My favorites were the shrimp scampi and lobster!

I don't like to give bad reviews but this time, I'll make an exception. Now, I wasn't expecting to have Maine Lobster. I was expecting little ones obviously. But the seafood upgrade gave us access to lobster, crab, shrimp etc. The lobsters were tiny quarters. About the size of the crawfish on the "basic" side of the buffer. The crab... More

This is the most over-rated item on the entire TripAdvisor site. I don't even know where a restaurant can get such a low quality of miniature crabs and lobster and other seafood items, I mean baby vegetables is a thing at some fancy restaurants, but miniature crab claws??? Really??? Voted #1 worst buffet in Nevada, I guarantee. They should have... More
