Kakao Sampaka Marunouchi Honten is a chocolate shop in Marunouchi Brick Square, near Tokyo Station. It serves Softcream Diagonale Blanco, a soft serve that contains sake ice cream and liqueur. Chocolate and cakes are takeout, while hot chocolate and chocolate soft serve can be eaten in the store. The store has only about two tables inside, so when it is crowded, the square's benches are used.
