This place started as a food truck but now also operates from the 2000 Penn complex. If tracking the truck down on Food Truck Fiesta is more stress than you can handle, just come up with daily excuses to go to the UPS store their permanent storefront is right by (“Karen! I can totally drop that package off for you!”). Once you’re there, choose from eight kinds of cookies, three flavors of ice cream, and milkshakes, little milk bottles, and giant cookie cakes (if you give them a few hours’ heads up). And if you ask nicely, they’ll even crush a cookie into your milkshake.
