Get on over there! It's on 49th and 4th. The slushie machine was broken when I stopped in on Tuesday, but they had plenty of the new Cappuccino and the old favorite Morir de Sonado. (Helado de Coco is always available!) Even the smallest size (for $1.50) is plenty to cool you off and change your mood for the better.
If storefronts aren't your style, just walk down 5th Avenue for some freshly shaved ice with your choice of flavors. The carts are out in force...on Tuesday there was one on every corner. The closer to the park the longer the lines, so try out 48th or 47th for a quick fix.
