Over the past few years, the craft of cocktail-mixing has attained the level of art form. Today's star bartenders crush fruit, ignite citrus peel, muddle tropical herbs, and intoxicate a thirsty public with an abundance of envelope-pushing complexity. 15 Romolo, a darkly elegant saloon tucked up an alley light years from the razzle-dazzle of Columbus and Broadway, stirs up libations visionary enough to bewitch the most jaded tippler. The Spaghetti Western, for instance, combines American rye and Campari with organic tomatoes and a splash of pilsner, the Eastwood ethos in a sippable format. Or consider the Hickory Dickory Dock, a fantasia of ginger beer, cream, Rémy Martin Cointreau Noir, and Pig's Nose blended scotch. Then there's the Fiscal Agent: bourbon, green chartreuse, maraschino liqueur, and sweet vermouth with a soupçon of cacao-nib tincture. Your barkeep might also get inspired by a root or berry from the morning farmers' market, so prepare yourself. These unique creations cost a mere $9 to $10 apiece, so start sipping.
