WWJD? Meaning, of course, What Would James Bond Drink? Odds are 007 would go for an elegant, classic martini, like the Imperial Room's Presidential, made with tasty Belvedere vodka and just the right nip of dry vermouth, or the Dirty Goose, which gets its salty kick from a dash of olive juice. This First Avenue favorite with the feel of a mod supper club also has frou-frou Sex in the City cocktails like the attractive, tangy Metropolitan and the rich Chocolate Kiss, made with white and dark chocolate liqueur. At $9, these beauties aren't cheap, but happy-hour specials (from 3:30 to 7:00 p.m. and 11:00 to midnight), make the Imperial affordable even to agents who aren't bankrolled by MI6. And, in any case, wouldn't Bond demand the best? Indishputably, Mish Moneypenny.
