My wife and I went to Le Diplomate by accident to celebrate our anniversary. After a disappointing result waiting in line at Little Serow on 17th St, we walked down to 14th St to check on some of our old favorite spots. Much to our surprise, fully formed from the head of Zeus, stood Le Diplomate, only three weeks into operation. The restaurant replaced a dry cleaners that, while a neighborhood staple, had rankled many concerned about the aesthetic and reputation of 14th St's rapid development. While it's sad to see old businesses leave, Le Diplomate offers what my wife tells me is an authentic Parisian bar and dining experience and what my stomach tells me is great food. We ordered the foie gras, braised duck, and lamb shank. All were fantastic. Entrees are around $20-25, but table wine, beer, and apps are reasonably priced for a relatively upscale restaurant.
While the overall service had the efficient feel of other packed-house behemoths in the area like Lauriol Plaza, the food outperformed older hats like Bistrot du Coin on Connecticut Ave. We arrived around 6 p.m. and only had to wait about 20 minutes before receiving a seat outside. We noticed large parties and couples getting seats relatively quickly throughout. One caveat is that the restaurant is predictably noisy. Those of you driving might have a tough time parking (though we walked there, we know the neighborhood gets pack to the gills on weekends).
