That's the spirit! Holiday shakes are now at Shake Shack

Through January 1, Shake Shack is serving up three delicious shakes: Pumpkin Pie (pumpkin pie blended with vanilla frozen custard topped with whipped cream and spiced pie crumble), Christmas Cookie (sugar cookie frozen custard topped with whipped cream and red and green sprinkles) and Chocolate Peppermint (chocolate frozen custard blended with peppermint and topped with whipped cream and chocolate peppermint candy crumble).

Don't sleep on the Brownie Batter Hot Chocolate either! Available through the winter season.
