Shake Shack

Here's the scenario: you're near Madison Square Park and it's winter, summer, spring, fall. Ok, just kidding. It's fall and you're suddenly realizing that your outdoor eating time is limited. Kick back in the greenery with a trip to Shake Shack's "Mothership in the Park." Easily one of the best grab-and-go options in town, as are its siblings dotting Manhattan from Battery Park to the Theater District, the Upper East, Upper West sides and beyond. Born out of humble hot dog cart beginnings, its menu promises and delivers everything from breakfast sandwiches to burgers and bird dogs to shakes and frozen custards. Update for the super-vigilant: the Chick'n Shack is made with 100% cage-free chickens, served on a non-GMO Martin's potato roll. Do it.
