White Castle burgers..?

White Castle, lol, it was like one of the big treats for us when my siblings and I were kids. Best I recall we went to, I think, Archer and Kedzie in Chi. They were like 10 cents each or so. Dad would by a couple sacks and drive us to Midway so we could watch the planes takeoff and land.
Another outfit closer to the airport show was Henry's that he liked. Not the same slider but we still got to watch the "air show".
