Which city is known for the Chicago-style hot dog?

The city known for the Chicago-style hot dog is Chicago, Illinois. This distinctive regional specialty consists of an all-beef frankfurter served on a steamed poppy-seed bun and covered with a generous collection of toppings.

A classic Chicago dog is topped with yellow mustard, chopped white onions, bright green sweet pickle relish, tomato slices, a dill-pickle spear, pickled sport peppers, and celery salt. The full arrangement is often called “dragged through the garden,” a reference to its abundance of vegetable toppings.

The style became especially associated with Chicago’s street vendors and Depression-era food culture. It is commonly served steamed or simmered, although a charcoal-grilled version is called a char-dog. One of its most famous rules is that ketchup is traditionally left off, a preference strongly defended by many Chicago vendors and residents.
