Key eras
1865 to 1971, the Union Stockyards era
The Union Stock Yards opened on Christmas Day 1865 on 320 acres of South Side prairie and made Chicago the world's largest meatpacking centre. By 1900, Armour and Swift packed more than half the meat eaten in the United States from Chicago. The yards closed in 1971 but the city's steakhouse culture, butcher-counter density and Italian-beef tradition all run back to them.
1943, the invention of deep-dish pizza
Pizzeria Uno opened on Ohio Street in 1943 under owner Ike Sewell. Original cook Rudy Malnati Sr., a Sicilian-American from Halsted Street, developed the pan-baked pizza with cheese under tomato to break from the East Coast slice and serve a meal rather than a snack. The Malnati family later spun off Lou Malnati's; Pizano's followed in 1991 from Rudy Jr. Deep-dish became Chicago's most-exported food fact.
1930s, Italian beef and the Maxwell Street market
The Italian beef sandwich was invented in Chicago in the 1930s among Italian-American workers on Taylor Street: cheap roast beef sliced paper-thin and ladled with jus on bread. The Maxwell Street market had been the immigrant shopping district since 1912; the Polish sausage counter and bagel cart both emerged there. Al's Beef opened in 1938; Mr. Beef followed in 1979.
1893, Vienna Beef at the Columbian Exposition
Austrian-Hungarian immigrants Emil Reichel and Sam Ladany introduced their all-beef frankfurter at the 1893 World's Columbian Exposition. Vienna Beef has made the canonical Chicago hot dog frankfurter ever since, with the dressed Chicago hot dog (no ketchup) crystallising during the 1930s Depression as a five-cent Maxwell Street vendor meal: a frank, salad, pickle and poppy-seed bun for a nickel.
2005 to present, the West Loop fine-dining cluster
Alinea opened on Halsted in May 2005 under Grant Achatz, a Charlie Trotter and Thomas Keller alumnus. By 2010 it held three Michelin stars. Around the same Fulton Market grid, Next opened 2011, The Aviary 2011, Smyth 2016, Oriole 2016, Ever 2020 and Porto 2022. The cluster around Randolph and Fulton became the country's densest concentration of Michelin-starred tasting menus outside New York and the Bay Area.
