Chicagoans are very particular about their hot
dogs. To begin with, it has to be an all-beef product, served on
a steamed poppy seed bun. But just as important are the essential
toppings. If you walk into a proper Chicago hot dog stand
and order it "Chicago Style," you'll get exactly these seven ingredients
on your dog: yellow mustard, chopped white onions,
neon green pickle relish, a dill pickle spear, tomato wedges,
sport peppers and, of course, celery salt.
