A Chicago-style hot dog, Chicago Dog, or Chicago Red Hot is an all-beef frankfurter on a poppy seed bun, originating from the city of Chicago, Illinois. The hot dog is topped with yellow mustard, chopped white onions, bright green sweet pickle relish, a dill pickle spear, tomato slices or wedges, pickled sport peppers (a variety of Capsicum annuum), and a dash of celery salt.
