Help! Dinner tonight in Rosslyn with kids
You don't have to go far, but you'll need to get out of Rosslyn.
Consider taking a very short taxi ride to the Courthouse area for Bayou Bakery (open until 8pm) for a short menu of New Orleans specialties. The Arm Drip Sandwich is outrageous. Or go to Me Jana (Lebanese) for the mezze platter. Not cheap, but extremely well executed.
Or Rays to the Third, for a Ray's Hellburger, the cheesesteak, or fried chicken. Also good steaks.
