Double Up Ice Cream is a takeout ice cream shop at the entrance of GARB Tokyo, a five-minute walk from the Marunouchi South Exit of Tokyo Station. It serves dense, chewy gelato such as rum raisin and marron glacé, ordered in a cup or a cone. Orders are placed and paid for at the counter, and the ice cream is handed over immediately, with cases of ordering without waiting. There is no seating inside the shop or on its dedicated terrace, so customers use the benches on Marunouchi Naka-dori across the street.
