Review for Rio Hotel & Casino Review For Carnival World Buffet Google User Aug 5 '18 at 4:38 With so many great places to eat in Las Vegas don't waste your money here. Yes, it's all-you-can-eat and yes there's a lot of different food, but the quality is not there. They do have crab legs but only until they run out and once they're gone, they're gone so unless you get there when they open you won't get any. If you do want all-you-can-eat I suggest the Indian restaurant in the same casino; smaller selection but the food is much better. View full site to comment or like
