Quick: Think of some of the beloved regional food items found in the Greater Boston area and elsewhere in New England. There’s clam chowder, of course, and lobster rolls, oysters, calamari and so many other seafood dishes. You have bar pizza on the South Shore, three-way roast beef sandwiches on the North Shore, New London-style pizza west of Boston and American chop suey, yankee pot roast and Boston cream pie at places around the area.
