There’s recently been a surplus of local pop-ups serving hot dogs topped with things like chili cheese, ranch Doritos, marshmallow fluff, and even glitter. But the original wiener joint in the state is Olneyville New York System, which has been making bright red wieners (don’t call them hot dogs) smeared with yellow mustard, topped with meat sauce, celery salt, and chopped onions, and served up in a warm bun since 1946. Order a few “all the way” and get a glass of coffee milk (pronounced “caw-fee”) while you’re at it. It’s a uniquely Rhode Island combination that you need to try at least once.
