Time Out says
This sophisticated food stall within Union Market comes from the Rappahannock Oyster team, a family-run company that produces over 1 billion bivalves a year. The first and only DC outpost does a swift business within this frenzied food hall. (Can’t find it? Just listen out for the “sluuuurps”.) Of course there’s oysters, but don’t overlook heftier dishes like lambs and clams, easily the restaurant’s most popular made with merguez sausage, sofrito, peas and aioli.
