Review for Rio Hotel & Casino Review For Carnival World Buffet Google User Jul 3 '18 at 18:25 One of the best buffets you will find in Vegas, especially if you are coming with family/children. There is something for everyone with dishes from around the world. TIP: Go for a late lunch, around 2ish and don't fill up too much because the food on the buffet gets changed out at 3pm. Buffet is cheaper before 3pm 😉 View full site to comment or like
