Trivia: Pickles are a key ingredient in what city’s hot dog style?
Chicago
Paris
Tijuana
Montreal
Correct Answer: Chicago
So why is this answer correct? : In the wake of the Great Depression, vendors in Chicago began experimenting with more creative — and cheaper — toppings for hot dogs, including pickles. The unconventional ingredient stuck, and today, traditional Chicago-style hot dogs are served on poppy-seed buns and topped with sliced dill pickles, yellow mustard, sweet pickle relish, chopped white onion, tomato slices, pickled sport peppers, and celery salt.
