Chicago farmers' markets, Chicago Dining, and Food Manufacturers of Chicago
Polish market in Chicago.Chicago can lay claim to a number of regional specialties, all of which reflect the city's ethnic and working class roots. Included among these are its nationally renowned deep-dish pizza, although locally the Chicago thin crust is also equally popular; the Chicago-style hot dog, typically a Vienna Beef dog loaded with an array of fixings that often includes Chicago's own neon green pickle relish, yellow mustard, pickled sport peppers, tomato wedges, dill pickle spear and topped off with celery salt (ketchup on a Chicago hot dog is typically frowned upon).25 There are two other distinctly Chicago sandwiches that can be found at eateries throughout the area: The Italian beef sandwich, which is thinly sliced beef slowly simmered in an au jus served on an Italian roll with sweet peppers or spicy giardiniera; and the Maxwell Street Polish, which is a kielbasa — typically from either the Vienna Beef Company or the Bobak Sausage Company — on a hot dog roll, topped with grilled onions, yelow mustard and the optional sport peppers.

Chicago's standing in the culinary world is not limited to 'street food', however. Featuring a number of celebrity chefs — a list which includes Charlie Trotter, Rick Tramonto, Jean Joho, Grant Achatz, and Rick Bayless, Chicago has in recent decades developed into one of the world's premiere restaurant cities.
 The grand tour of Chicago cuisine culminates annually in Grant Park at the Taste of Chicago, a festival that runs from the final week of June through Fourth of July weekend. 'The Taste', as it is abbreviated by locals, showcases Chicago's ethnic dining diversity as well as all the locally favorite stalwarts (see above). Booths representing myriad local eateries form the centerpiece of the city's largest festival, which draws millions each summer to sample the cuisine, while enjoying free concerts and fireworks.
