Review for Rio Hotel & Casino Review For Carnival World Buffet Google User Jun 15 '18 at 23:25 This Buffet has seriously gone down hill. They no longer serve crab legs or any of the great seafood they used to. I took my wife there last night and I wish I would have gone else where. This place is not worth the $30 a person it once was. not even close. this is no better than any of the off strip buffets that you can go to for a much better price. Such a shame. I used to love this place. View full site to comment or like
