If there’s a more storied sipping spot in DC, we don’t know it. The lobby level of the Willard InterContinental has been wetting whistles since Abraham Lincoln was in the White House. Today bartender and cocktail historian Jim Hewes—a 27-year Round Robin vet—presides over the 360-degree, polished-wood bar, enlightening guests on the history of the city, the hotel, and the contents of their glasses. Scotch fans, take note—Hewes has curated a menu of 100-plus bottles organized by region and all available at the adjacent Scotch Bar. Insider tip: Opt for a mint julep: The modern version of the minty drink was popularized at this very spot, when statesman Henry Clay insisted that his julep, then typically made with cognac, feature bourbon instead. Round Robin open daily. Scotch Bar open Monday through Saturday.
