Just when the Upper East Side residents were beginning to think they weren’t loved by the people who run the beloved and applauded Shake Shack eateries, they can now breathe easily because come Friday, Shake Shack Upper East Side officially opens on East 86th Street. The Shack’s new home is nestled within a unique garden plaza between Lexington and 3rd Ave, where guests can relax and enjoy Shack burgers and frozen custard morning, noon and night. Along with all the original Shake Shack favorites, the menu will feature Upper East Side inspired additions like the ‘Coffee Bean Brownie’ (Vanilla custard, brownies, coffee, caramel, whipped cream), ‘Chocolate Peanut Butter Crunchcrete’ (Chocolate custard, peanut butter sauce, chocolate toffee, chocolate sprinkles) and the ‘Pineapple Upper East Side Cake’ (Vanilla custard, fresh pineapple, shortbread, caramel, maraschino cherries.) Now the Upper East Side is really privileged. www.shakeshack.com
