This was the first restaurant for Wellfleet’s Hay brothers, who have four fish markets and three restaurants (see Mac’s Shack). It is a no-fuss take-out clam shack, perfectly located on the Wellfleet pier. You order from the window and find a picnic table on the sand, steps from the lapping waters of the harbor. It is dining alfresco, Cape Cod style. The usual fried fish dinners are here, but there’s also grilled tuna with summer vegetables, fish tacos, and even jambalaya. Ice cream, both soft-serve and hard, gets its own window.
