Has anyone ever had or ordered National Chili Sauce from the National Coney Island company in Detroit?

National Coney Island currently owns and operates 20 restaurants in Southeastern Michigan and has been in business since 1965. The corporate headquarters are located in Roseville, Michigan, home of the original location! I’ve been Jonesing for some GOOD Coney Sauce on hot dogs for some time and thought I would give them a try.

I have a good recipe but not enough ambition to make it.
