If the walls of Radio Bar could talk, they'd sing like Chet Baker and laugh like Marlene Dietrich. The indigo interior combines elements of traditional Japanese design with Art Deco ornamentation, and exudes an air of Hollywood in the fifties. The space is seductively dim, conducive to tete-a-tetes and true confessions.

Radio Bar serves some of the most elegant cocktails in town, expertly mixed by Koji Ozaki and his team of white-tuxedo-attired bartenders. The focus is on the classics, served in antique glassware. Ozaki's martini is crisp and succinct, with a note of vermouth hovering above the gin. The dry Manhattan is a grown-up affair - dark, smooth and not in the least bit cloying.

Original cocktails include the Dean Martin, an unlikely but delicious blend of Campari and Jack Daniels, and the Greta Garbo, a dry martini with a sherry kick. Prices range from Y1,300 to Y2,000, but note that there's a seating charge of Y1,000 per person.
