Hakodate's iconic burger shop has been voted best in the nation several times – despite its cultivated dive image. The house special is the Chinese chicken burger, an oddly addictive combo of twice-cooked chicken, crisp lettuce and mayonnaise on a sesame bun. Much of the menu is similarly fusion; the decor is carnival diner c 1989.
It has several branches around the city, but this is one of the bigger ones, conveniently located near the bay front.
