Red Apron, web site, locations in Angelika Mosaic, 7th and D Streets NW (attached to The Partisan), and Union Market, sometimes they close fairly early in the evening. (Metro Trip Planner – opens in new window) [WaPo | Washingtonian | City Paper | Ylp | Don Rockwell | Gayot]
They offer a limited number of quick-serve entries based on high-quality meat products, with prices below restaurant level but much more expensive than fast food. They also sell sausage, pates, and other meat products, again high quality offerings, red wine too. I find this a very useful outlet for both shopping and eating, especially in Angelika I often grab a hamburger here before seeing a movie. I never feel it is the very best burger around, but somehow it stands up to repeated samplings more than the “better” burgers do. While this is a place of limited scope with limited uses, it is actually one of the restaurants I eat at the most.
