We did the Buffet of Buffets offer - unlimited buffets at all the Harrah's properties for 24 hours for $45. If you are a foodie this is the way to go.
Gellato was one of my favorite things here plus the server was on par and good. They have a wide selection of items to choose from. I was pretty pleased with it. Since we stayed at the Rio (Don't do that and see my review on the Rio itself) we ate here a lot as it was close and convenient. It was not as crowded as the hotels/buffets on the strip but they do get a considerable line around lunch/dinner time.
Worth the time to go here.
