I remembered them for 10 cent burgers back in the early ‘50s. Went there after roller-skating. All we could afford, 50 cents for skating, 25 cents for 2 burgers and a Coke, about 25 cents for gas. Nice evening on a buck a person.
I remember 15 cents in Detroit. Now 70 cents in St. Louis. They still taste the same. Love them sliders. :-D
Frozen White Castle sliders still can be purchased at most supermarket chains......and I still buy their cheeseburgers now and then, putting a bit more of my own ketchup and onions on them, but they lose a little in the microwave transition, unfortunately....mostly bun-wise and soggier.
