Part of David Chang’s Momofuku empire, this hipster dessert bar is the home of Pastry Chef Christina Tosi’s eclectic sweets. Cereal milk soft-serve ice cream, made decadent by corn flake–soaked milk, is the signature dessert to try in store. More easily transportable items—birthday cake truffles, compost cookies (featuring potato chips, pretzels and coffee grounds) and a slice of crack pie—may just survive the journey back to the Hotel, if temptation doesn’t strike.
