There's no denying that the hot dog is a major food group in Chicago, right next to Chicago deep dish pizza. The best Chicago hot dog restaurants crank out red hots topped with mustard, onions, relish, pickle spears, tomato, sport peppers and celery salt. (If you didn't already know, those are the key ingredients in a true Chicago-style dog.) Of course, there's room for creativity, and many of the top Chicago hot dog restaurants also experiment with toppings like foie gras, kimchi and even—gasp!—ketchup. Lucky for you and your wallet, these sausages are among the best cheap eats in Chicago—even more reason to scarf down a red hot while checking out classic Chicago attractions. Scope out the best Chicago hot dog restaurants and don't forget that mustard is the best condiment and that fries are always encouraged.
