A new cocktail bar will be opening near Dupont Circle. McClellan's Retreat (named after the Union Civil War general, whose equestrian statue is nearby) is located at 2031 Florida Avenue NW. This space was previously home to Veritas Wine Bar. It's just a few doors down form Russia House and a stone's throw from the Washington Hilton Hotel.
The McClellan's Retreat website describes the new venue as "...a place to retire, retreat, a place to saddle up to the bar and enjoy a lovingly made cocktail, a strong drink, a savory snack and a bit of conversation." The online menu isn't quite filled out, but does include classic cocktails like the Manhattan, the Rickey, and the old fashioned. The listed hours are 4:00 PM - 2:00 AM, daily.
No word on opening date, but they were working hard to put on the finishing touches when I peeked in late last week. Good luck McClellan's Retreat!
