I came here yesterday after lounging at Nikki Beach. The place is part of the South Beach Marketplace and it has both Gelato and self serve frozen yogurt. They charge 49 cents per oz. which is quite pricey, but then again, it IS inside a casino.
I ended up getting Dulce de Leche, Cheesecake, Peach Mango, and Plain. My favorite was definitely the Peach Mango because it was the closest to a tart flavor. The Dulce de Leche was also good, but I'm more of a tart person. Don't be fooled by the plain flavor. I guess I just assumed it was going to be "plain tart," but I was wrong. The plain flavor is exactly as titled, PLAIN. It literally tastes like nothing, so I would suggest not getting it. Even though their toppings selection isn't very big, the fruits were very fresh. You could tell they have them delivered fresh as opposed to getting frozen fruits to thaw and serve.
I tried to limit myself on the froyo since I saw that it was 49 cents per ounce, but it still came up to $5.17. Since it adds up so fast, I think I'll just stick to Gelato next time because it'll probably be cheaper.
