Mark I apologize for this, but I'm curious as the dickens to find out where you are located with that reference to White Castle Burgers.

When I discovered White Castle in Mississippi back in 1860 or so we had Royal Castle and Krystal burgers on Canal Street in New Orleans, which were identical to the White Castle Burgers. The only Krystal Burger I know of now is in Hattiesburg Mississippi where my in-laws live. Royal Castle has long ago left New Orleans.
Thanks Mark
