Chicago is a city that adores its food icons. From pizza, to Italian beef, to hot dogs "dragged through the garden", the Windy City is an international beacon of intensely lionized foodstuffs. But there's one Chicago food tradition that flies so under-the-radar, even many Chicago residents hadn't heard of it before Chicago-born comedian Hannibal Burress penned a love letter to it in Chicago Magazine in February 2017. "If you live on the South Side or West Side and you go to a restaurant that has bulletproof glass, they probably have mild sauce," he wrote. "It should have Sriracha levels of fame."
