These Raspados shops have been popping up all over town lately. This place is the first one my wife and I tried, and it was amazing the first time we went.
Not only are all the combinations of ice cream, shaved ice, fruit, etc really really good, but they have an assortment of salty snacks like Tostitos de Elote, which are really awesome as well.
There is one problem: the prices have gotten insane. We first started going here, and while it was never a cheap snack, it wasn't too bad. We recently went back and spent over $8 on one dessert which used to be closer to $5-6. With all the other Raspados shops around now, I'd say you can travel just a short distance to find the same treats at better prices.
