The Chicago style hot dog is a fast food staple throughout the Windy City's sphere of influence. Outsiders think the concoction is weird, but the combination of mustard, onion, neon green relish, a dill pickle spear, tomato, sport peppers, and celery salt takes a hot dog to a different level. This particular specimen is from Mitch's Chicago Style Grill and was quite tasty. Though for my money, the best Chicago Dogs anywhere are found at Portillo's. Unless you're one of those people who would dare put ketchup on a hot dog, the Chicago Dog should be a lunchtime favorite.
