William Greenberg Desserts

Bakery in Upper East Side

Stop in at this Manhattan institution for its signature New York–style black-and-white cookies – soft, cakey discs dipped in vanilla and chocolate glazes (grab a box of minis for the trip home). Classic egg cream sodas come in four flavors; its brownies are divine, too. Take-out only. There's a kiosk in the basement food hall of the Plaza Hotel.
