I like the RIO Village Seafood Buffet, on a weekday for dinner it's $44.99 (and if you sign up for or have a gambler's tracking card, you get $1 off).
It's a grand buffet, with lots of options. I think the non-seafood buffet at The Rio is about $10 cheaper and is in a different location than the Seafood Buffet.
The Seafood is okay. Typical snow crab legs, fishes, shrimp and other stuff. The Lobster wasn't very good, it was I think what's called "Mexican Slipper" lobster which is smaller and not as tasty. I'd have preferred also to have "Dungeness Crab" a favorite for those from the North in San Francisco or Portland or "Alaskan King Crab" which is a higher quality to the "Snow Crab" which you can get at any Asian Buffet and has become a common run of the mill menu item for all buffets in general.
The prime rib roast beef as good, but I know can be hit/miss depending what cut they roast and if it's overcooked or done to a medium rare perfection. The 1st slice I had rivaled what you'd pay $20-30 for at a restaurant, very juicy and flavorful. The 2nd slice I went to try later on was a bit of the tougher and drier style and tasted like a different lower quality cut of meat than the 1st.
They have international cuisine, Chinese Asian (featuring Roast Duck too), Mexican, Italian and American standard fare. They have ice cream as well. Not a robust salad bar, nor soup options or deserts to brag about.
It's always a balancing act of decision making when deciding whether to dine at a buffet VS non-buffet standard dining. You factor in 1) Price; 2) Service Convenience; 3) Location Convenience; 4) Appetite; 5) Quality.
So, for roughly $55 (after you tip 'em and pay your tax too) the question is.. Can you get a better meal where you just order an entree elsewhere?
For those who can't eat $50+ worth of food, maybe the answer is "no"
For those who can eat a lot, who also enjoys tasty diverse flavors (so, if you went to a restaurant and ordered a prime rib with snow crab legs and then added in appetizer and desert with a drink, you'd pay more than $50 at most places), this is a good place.
There are other buffet options in Vegas too, some cheaper, some slightly more expensive ('tho $50 is generally the higher end), and all varying in quality of food and diversity of selection. I generally like the Wynn's Buffet which is the same price. I like the Rio's better than TI's buffet and may other places 'tho.
I think this is an okay deal at $50 (and for you gamblers out there who flippantly peel out $100's betting the cards, dice or slots, only to lose in mere minutes... treat yourself to a good meal and you should never be cheap eating when you're gambling the same or more money seemingly recklessly... get your priorities straight and eat well n' enjoy!)
If this were priced at $30 or below that would be right sized and perfect in my opinion however.
The Rio's location is off the strip, so you need to take a cab or drive generally.
