It's cool because they have a good selection of ice cream flavors, including some Mexican ones, a good selection of aguas frescas, and a good selection of other desserts and snacks that I'd never heard of (churros locos?? chamango? tostilocos - looks like a bag of tostitos with a bunch of toppings thrown in, served with a fork!)
On the other hand, it's not that cool because it's pretty dirty inside. I'm not one of these health Nazis, but even I was a little put off by the stains on the cloth bar stools.
Prices have increased since some of these other reviews. I got 3 small ice creams (single scoop each) for just over $10.
Might go back and get an agua fresca to go....
