MAISON CACAO Gransta Tokyo Store

Maison Cacao is a chocolate shop inside Gransta, within the JR ticket gates at Tokyo Station. Its aroma nama chocolate comes as one flavor per box, chosen from more than ten flavors, and the Gransta Tokyo store also sells a pistachio gateau chocolat exclusive to that branch. The brownies are meant to be heated in a microwave for 15 seconds, and the pistachio gateau chocolat can be kept at room temperature for 20 hours. Prices run high, so it is a burden for a light purchase.
