Italian Beef in Chicago: The Gravy Flows Like Wine

When it comes to Chicago food, most people think of deep dish pizza or hotdogs sans ketchup, but the Italian Beef sandwich is a huge part of the Chicago palette.
Believed to have been invented in the 1930s, poor people would slice less choice cuts of beef (from the Union Stockyards of course) so thin you'd have no idea how un-choice the meat is. They would put it on day-old bread and dunk it in the gravy so you'd have no idea the bread was day-old.
This episode is a love letter to all the Italian beef restaurants in Chicagoland.
