Hi, where could i get information about getting an international franchise for a white castle restaurant?
I have tried their website , but they just mention that they dont have franchises in the U.S. , but they dont say how to contact them to open a franchise out of the U.S., Thanks any info would be helpful.

Their website sort of implies that they only operate in the US. They mention exporting products to Mexico but don’t mention having restaurants there. It looks like they’re just in 11 states, so if they haven’t spread out more than that, are very possibly not interested in going international.
