Time Out says
Fruit fans can get their smoothie fix at this juice bar located down Shibuya’s back street of Nonbei Yokocho. Specialising exclusively in banana drinks, try the signature Rich Banana Juice which uses ripe bananas and milk from the Kuzumaki Kogen Farm in Iwate prefecture. The bananas are frozen before being blended with the milk to create a thick smoothie. If that's not enough, you can add extra mix-ins including protein powder, coffee, or even acai berries to give your thirst-quenching drink an added boost.
