Bistrot du Coin (Corner Bistro) has been a go-to place for years, whenever I find myself in Dupont Circle. In past years, it was consistently very good. This year, things seemed a bit more tired and careless. Food (steak maison and steak tartare) still quite good; red wine by the glass was fresh and delicious (a frequent problem at other places that have a dozen or more open bottles sitting around, but this one tasted like a freshly-opened wine). But the décor is dated, bathroom out of service, everything just looking like a good cleaning and updating would help.
