Providence Rhode Island, an hour south of Boston by train, is the New England food deep cut. Olneyville New York System hot wieners since 1946, Bacaro for Italian, the Iggys Doughboys empire.
Tip: Olneyville closes at 02:00 weekends; the 'all the way' wiener is the order. Take the Acela back to Boston after dinner.
Portland Maine, two hours north of Boston, is New England's most decorated food city. Eventide Oyster Co, Fore Street, Duck Fat and a 100-restaurant Old Port; the lobster-roll heartland.
Tip: Amtrak Downeaster from North Station runs five round trips a day. The brown-butter lobster roll at Eventide is the must-eat order.
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.
Salem, 30 minutes north of Boston on the commuter rail, mixes Halloween tourist food with serious North Shore seafood. Turner's Seafood for clam chowder and Bertini's clam shack in Beverly.
Tip: October is peak tourist month; the food scene runs year-round. Take commuter rail to skip parking.
Ipswich and Essex on Boston's North Shore are the original fried-clam towns. Lawrence Chubby Woodman invented the dish in Essex in 1916. Woodman's, the Clam Box in Ipswich and J.T. Farnham's are the trio.
Tip: Summer weekend lines at Clam Box and Woodman's run 60 to 90 minutes. Visit weekdays before 17:00 for the easy seat.
Newport Rhode Island, 90 minutes south of Boston, is the New England summer seafood capital. The Black Pearl on Bannister's Wharf, Flo's Clam Shack in Middletown, and the Newport mansion tour for context.
Tip: Drive only; no train. Combine with the Cliff Walk for a long food-and-history day.
