quote from WikiPedia:
White Castle Management Co. is an American regional fast food hamburger restaurant chain located in the Midwestern and Southern United States as well as in the New York metropolitan area, generally credited[citation needed] as the first fast food chain. It is known for its small, square hamburgers. Sometimes referred to as "sliders", the burgers were priced at five cents until the 1940s, and remained at ten cents for years thereafter. For several years, when the original burgers sold for five cents, White Castle periodically ran promotional ads in local newspapers which contained coupons offering five burgers for ten cents, takeout only.
On Jan. 14, 2014, Time Magazine labelled the White Castle slider to be the most influential burger of all time.[2]
I'm curious as the dickens to find out where you are located with that reference to White Castle Burgers.
Boo...I'm in the Northeast somewhere near "one-man-band alley".....Uncle Dave, Bill Lewis, Sparky, Donny, etc. I understand Don M (our Chairman of the Board) is retiring up here soon to be with "family."
When I discovered White Castle in Mississippi back in 1860
Most White Castle hamburgers taste like they were cooked in "1860" and sold in 2014.
.....so we had Royal Castle and Krystal burgers on Canal Street in New Orleans, which were identical to the White Castle Burgers.
....but without the "agida!"
The only Krystal Burger I know of now is in Hattiesburg Mississippi
.....BUT.....a hamburger is not really considered a "classic" until it makes big it in Hattiesburg, Mississippi!!!
