There is a popcorn store in the suburban town of Wheaton that makes (imho) the best popcorn. It is not flavored but is truly delicious. It has been there for almost a hundred years. Built between two buildings the store is only five feet wide. They sell penny candy (paper dots, licorice, gum cigarettes) and popcorn - nothing more. A gigantic bag is only five bucks! Take the train to Wheaton and just ask somebody for directions to "The Popcorn Store". Then sit by the fountain across the street and enjoy.
