Just a trivia question that I don't know. The 1st Mcdonalds was built in Des Plaines. Does anyone know where the 1st Burger King was established in the Chicago area? I remember a old Burger King that use to be on Belmont just west of Austin that had the old sign up when it closed. The 1st ever Arby's has never changed, it is in Palatine with the cowboy hat roof on it. Just a crazy question!!!!!!!
