Some locations along Route 66 in Illinois became known for their cuisine. One example is the state capital, Springfield. The city has long had an affiliation with food. The corn dog on a stick was invented in the city under the name "Cozy Dog", although there is some debate to the actual origin of the popular snack. The Cozy Dog Drive In has been a Springfield Route 66 staple since 1950. One of the first U.S. drive-thru restaurant windows is still in operation in Springfield on Route 66 at the Maid-Rite Sandwich Shop.
