Review for Rio Hotel & Casino Review For Carnival World Buffet Google User Jan 19 '16 at 2:55 Been hear many times in the past, always pretty good. Got there and it was extremely hot in the restaurant. Asked for a cooler area and they put us right by the kitchen. Awful. Food was also very bad, nothing like it used to be. Won't be back. Go to the Mirage (Carvings) buffet. View full site to comment or like
