Chicago’s food identity is built on a handful of dishes that locals defend with near-religious intensity — and knowing the unwritten rules around each one will save you from some very pointed local corrections.
Deep Dish Pizza: A City Divided
Deep dish pizza, invented at Pizzeria Uno in 1943, remains Chicago’s most famous culinary export, though locals are quick to point out it’s more of an occasional treat than a weekly habit — the thick, buttery crust, layers of cheese, and chunky tomato sauce on top (rather than underneath, as in traditional pizza) makes for a rich, heavy meal best shared. Lou Malnati’s and Giordano’s are the two most commercially recognizable names, both with multiple locations and near-identical reputations, so the “better” choice largely comes down to personal preference rather than any objective difference. For a less touristy option with equally devoted local fans, Pequod’s Pizza is known for its caramelized, slightly burnt cheese crust edge, a signature that regulars specifically seek out.
The Chicago-Style Hot Dog: Rules Are Rules
The Chicago-style hot dog is defined as much by what it doesn’t include as what it does: an all-beef frankfurter on a poppy seed bun, topped with yellow mustard, chopped white onions, bright green relish, a dill pickle spear, tomato slices, pickled sport peppers, and a dash of celery salt — and, crucially, never ketchup. This isn’t just preference; ordering ketchup on a hot dog in front of a Chicago vendor is likely to draw genuine (if good-natured) protest. Portillo’s, a Chicago institution with locations throughout the city, is the most accessible place to try a proper Chicago dog alongside an Italian beef sandwich, but smaller, independent stands scattered throughout residential neighborhoods often serve versions locals consider even better.
Italian Beef: Chicago’s Underrated Sandwich
The Italian beef sandwich — thinly sliced, slow-roasted beef piled onto a long Italian roll, typically dipped in the meat’s own seasoned jus and topped with either sweet peppers or spicy giardiniera — is arguably Chicago’s most underrated culinary export outside the city, despite gaining wider recognition after the TV show “The Bear” (largely filmed around and inspired by Chicago’s real Italian beef shops) brought it to national attention. Al’s Beef and Johnnie’s Beef are two of the most established names, with loyal, long-running followings and a decades-old rivalry over which serves the definitive version.
Beyond the Classics
Chicago’s food scene extends well beyond its famous trio. The city has one of the country’s most vibrant fine dining scenes, anchored by Alinea, a three-Michelin-starred restaurant known for boundary-pushing, avant-garde tasting menus that have made it one of the most talked-about restaurants in American fine dining. For something more accessible but equally beloved locally, the Maxwell Street Market, a Sunday open-air market with roots dating back over a century, is one of the best places to sample Mexican street food, particularly its famous Maxwell Street Polish sausage, alongside live blues music that echoes the market’s historic role in the development of Chicago blues.
Practical Notes
Most of Chicago’s iconic food spots are casual, counter-service establishments where reservations aren’t needed or accepted, though popular deep dish restaurants can involve a wait during peak dinner hours on weekends. Prices remain reasonable by major-city standards — a full meal at most of these spots runs $10-20 per person, making a self-guided food tour across several of these stops an affordable and thoroughly satisfying way to spend a day in the city.
