Cape Cod (Wellfleet and Chatham) ★ 4.7
Cape Cod's outer flats produce Wellfleet oysters, the East Coast benchmark; Chatham boats land day-boat scallops at the Chatham Pier Fish Market. Summer lobster shacks run from June to September.
Tip: Mac's Shack in Wellfleet for raw oysters; Chatham Pier Fish Market for scallops to take home. Summer-weekend traffic peaks Friday and Sunday afternoon.
