Here is one from the past, do not know if it still exists. In Evergreen Park Illinois on Western Avenue around 85th Street. Called Snackville Junction. Customers sat at a long u-shape counter. All food was delivered on a Lionel O-guage that pulled flat cars holding plastic baskets. The train ran in a loop through the out-of-site kitchen across the counter top in front of each seat. With a caboose.
