definitely the RIO, they have everything you could want there and it is $29.95 and starts every day at 4pm

I have been there NUMEROUS times

Rio has a good one it's 26-27 per person (I think). Rampart Casino has one on Thursdays but its way off the strip (near my house). However I can't eat seafood anymore .

There's no contest.  Rio is where you should go.  Yes, it is pricey, but when you see the quantity and quality of the food, you will understand the price.  Bon Appetit!

Best for selection:  The Rio wins hands down.  If you're new to the hotel, it is NOT inside the main buffet, but rather on the opposite side of the casino at far end of the shoppes.

Best for quality:  Bellagio.  The selection is much smaller and it is served as part of the main buffet, but in this case less is more.

Thanks Guys and Ladies ! Looks like the Rio it is . I'll be sure and visit it one maybe 2 times   when I come out May 15th thru 20th. Have a great week everyone !! MrEd42
