Gen Yamamoto takes the seaonal tasting menu concept and applies it to cocktails. Here they're made with fruits and herbs, with the same kind of devotion to presentation seen at restaurants serving kaiseki (Japanese haute cuisine). Choose from sets of four (¥4800), six (¥6900) or seven (¥7800). Fear not, they're designed to be savoured, not to get you sozzled (servings are small).
The bar is just eight seats at a counter made from a 500-year-old Japanese oak. Reservations (possible from one week in advance) recommended; cover charge ¥1000.
