I've always seen these at DisneyLand and never would have gone for it, but since we were waiting outside the Tiki Tiki Room, we all got one to share. It was pretty good! It's a cup full of pineapple juice with pineapple frozen yogurt, an of course topped with a maraschino cherry.
It's no Mickey ice cream bar, but it's good. I would not recommend sharing though...backwash, ew.
