One of the most fascinating aspects of Chicago’s breakfast culture is its connection to history. The city was home to the world’s first-ever all-you-can-eat breakfast buffet, introduced in the 1940s at the Sherman House Hotel, setting the stage for the extravagant brunches we know today. Chicago is also the birthplace of the original fast-food breakfast sandwich—McDonald's Egg McMuffin, developed by Herb Peterson in the early 1970s, was inspired by eggs Benedict but designed for people on the go. Today, Chicago’s love for hot breakfast continues with a mix of historic diners, chef-driven brunch spots, and modern cafes. Whether you're looking for a hearty Southern-style breakfast, a plate of gourmet pancakes, or a perfectly crafted eggs Benedict, here are the must-visit restaurants in Chicago to celebrate National Hot Breakfast Month.
