One of the more unique Vegas food experience was IcePan
We happen to see it because on our way from the Monorail to the street, it is next to the Starbuck before the escalators.
It's kinda unique, you pick a base flavor and they make the ice cream right there. Then you pick the type of diary you want, so if you're lactose in tolerance, you get your choice of what you want. Then you get toppings. For an extra charge, you can have more toppings.
Check out the video I took of the lady making our ice cream:
As you can see, this is all done under 2 minutes. Pretty unique.
I got Pistachio as my base ice cream with soy milk, then I picked mochi (rice balls) with chocolate drizzle. This is a very fascinating way of customizing your ice cream down to the diary that goes into it. You couldn't ask for more.
