Serving raw oysters on the half shell, classic cocktails and beer and wine, Dylan's Oyster Cellar has taken up a six-month residency in The Hatch, the incubator space in Mount Vernon's Park Plaza Building operated by Phil Han, the owner of Dooby's. The pop-up oyster bar is from Dylan Salmon, formerly of Woodberry Kitchen, who plans to operate at The Hatch for six months while he scouts out a permanent location.
