For decades, this white-clapboard seaside building was known as the Wayfarer, and for most of that time, it was a low-frills fishermen’s diner. It’s changed hands and concepts a few times more recently, but not until former White Barn Inn executive chef Jonathan Cartwright took it over in 2018 did it hit the sweet spot between chefy and unfussy. Breakfasts are simple and mostly savory: benedicts, corned beef hash, bagels and lox. Lunches are elevated diner fare: grilled cheese with fontina and bacon, a brown-butter lobster roll. The short dinner menu favors what’s local, seasonal, and comforting: expect Maine scallops, roast chicken, cavatelli with Maine-foraged mushrooms. Specials might be fish tacos or hot dogs topped with house coleslaw, as suitable for casual takeout as for dinner in the cozy, rustic dining room, which feels a lot like Cape Porpoises’s living room.
