This is a vivid dark-red pork dog, on the small side, steamed, served on a microwaved split top bun (grilled dogs are available on request). Cheese, sauerkraut, and chili are available here, but the traditional condiments are relish, onion, and ketchup. One unusual touch: a shaker of celery salt is offered along with the salt and pepper. Simone’s has been selling dogs and other simple fare since 1908, and judging from the photos on the wall, every politician in or from New England has been here at one point or another.

Flo’s Hot Dogs in Cape Neddick, Maine, is a family-owned and operated establishment that has been in business since 1959. They specialize in steamed hot dogs that only need a sprinkle of celery salt, relish, and mayo. The relish is famous, although the recipe is secret, and is sold separately in jars both on location and online. The classic joint is open year-round, with the exception of Wednesdays, but it only operates from 11 a.m. to 3 p.m. Pro tip: ketchup isn’t available, so don’t ask for it. The hot dogs have a spicy natural casing, and the secret relish is at once spicy and sweet. Know what you want to order by the time you get to the front of the line, and look for a spot at the six-seat counter inside, but if it’s full (as it normally is), don’t worry — picnic tables are provided outside.
