Gilley’s PM Lunch, Portsmouth, NH
Gilley’s could be called one of the original food trucks. In the mid-1900s, the wheeled cart was pulled into Portsmouth’s square daily by a horse and then a tractor. While it has since found permanent digs (with eight barstools and outside seating for hundreds), gourmet hot dogs continue to be a staple. “We still grill the same local Schultz hot dogs,” says current owner Steve Kennedy. “It’s a beef pork and veal blend with the original toppings of ketchup, mustard, relish, and onions.” Another classic: its three-ounce hamburger patty, which comes with a small steamed bun—no lettuce, no tomato, no fuss.
