Can a place that rolls sushi really be considered a clam shack? For the Net Result, we’ll bend the rules. The legendary Vineyard Haven fish market deals in only the freshest catch—its suppliers drop off their hauls several times a day—including shrimp, sea and bay scallops, king crab, squid, and scrod. The takeout counter hawks overstuffed lobster rolls and heaping plates of crispy clam bellies, oysters, and assorted other crustaceans and bivalves. And, yes, the sushi’s pretty damn good, too.
