From the Ice Cream Sandwich Heavens comes Cool Haus.  A shiny silver box on wheels has delivered the most interesting ice cream sandwiches.  Cool Haus Ice Cream Truck gives options and who doesn't love options when it comes to ice cream.  First step, choose a cookie, second step choose your ice cream and third step choose the top cookie. Yes ladies and gents you can have one cookie on the bottom and a different cookie on top.  While I haven't had everything, I can tell you the dark chocolate cookie is delish. The Green Tea Ice Cream is seriously the best Green Tea Ice Cream in the city. If you get to them early you'll get their edible sleeve.  The sandwich comes in this white paper that is not paper to toss, but paper to eat. Lately, they are at the 30th st lot at the end of the High Line.
