You're going to need a tie — and not that sartorial disaster you keep on the back of your office door in case of an emergency meeting. Because if you're going to enjoy sipping an Old Fashioned at the dark, brick-walled R Bar, you should look like you were plucked from the pages of Esquire. An amber galaxy of flavor served in a heavy tumbler, made with toddler-age Old Overholt rye whiskey and Angostura bitters, this Old Fashioned is a drink that knows how to match shoes with a belt. A thick disc of orange splashed in the middle of the glass offers sophistication that a flimsy wedge never could. A single cherry hunkering among the ice cubes adds a touch of color and slow-release sweetness that never threatens to overtake the rye. And when you're finished — it will take longer than you think — remember that a gentleman never eats the fruit. Simply order another, but probably not more than two. Even the most established man has a budget, and at $9 a pop, it's perfectly acceptable to switch to beer when the tumbler runs dry.
