Mac’s has become an institution in the Outer Cape, thanks to several restaurants and fish shops. The main restaurant, Mac’s Shack, is located in a 19th-century nautical shop in Wellfleet with a model of a lobsterman on the roof. Come here for the freshest sushi, as well as crudos and oysters on the half shell. Set on the Wellfleet town pier, Mac's on the Pier has a takeout window. Grab a lobster roll or a plate of steamers and devour it all at a picnic table by the water.
