The Old Imperial Bar is an old-school Tokyo bar favored by some of Japan’s political and financial elite, who come for its demure and consistent service. The popular bar snack kaki pi—spicy rice crackers and peanuts—originated here and is still being served. Soak in the nods to Frank Lloyd Wright, who designed the original hotel: the Hopi-inspired carpet design, the terra-cotta grillwork, and the polychrome and gold-leaf fresco on the wall in the back of the room. Classic cocktails reign, such as a gin and tonic made with the Kyoto-distilled gin Ki no Bi, with notes of yuzu, green tea, and ginger.
