The newly opened Food Depot in the basement of Shinjuku's Lumine 1 department store features a lot of intriguing eateries, with a number of dessert shops among them. Ca Ca O, a chocolate store originally from Kamakura, Kanagawa Prefecture, offers a variety of goods made from rich cacao beans. The Ca Ca O eclair (¥350), available for the first time outside the original Kamakura location, is the way to go. It's heavy on the store's trademark cocoa, with sweet cream and crunchy chocolate chunks surrounded by a soft cake. If you need to satiate your sweet tooth on your way through Shinjuku Station, this is a good takeaway option.
