Here is a photo of the "White Castle," at 7155 Ogden Ave., Berwyn, Illinois on old Route 66. They opened on January 14, 1939. This is the oldest White Castle still operating on Historic Route 66. Here you could get a 5-cent slider to eat at the counter or take some along on the open highway. White Castle was the first food chain in the nation to standardize buns, burgers, and buildings. Spotless buildings, interiors, and uniforms reassured customers that the food was clean and pure in an era when people feared poor meat packing sanitation. And they are still in business at this location today. This photo is courtesy of the White Castle Collection and 66postcards.
