Does anyone know how coney island hot dogs got started? Who came up for the name [[I assume a reference to NYC Coney Island Park, where they serve hot dogs)? Who first served a dog smothered in chili and onions and called it a "coney island?" And why are so many of Detroit's coney island restaurants run by Greeks who also serve Greek food?

I am working on an "Unconventional Guide to Detroit" and would love to know the origin of this peculiarly Detroit custom of putting together a hot dog. My own coney island favorite is a bowl of coney island chili smothered in chopped onions and shredded cheddar cheese. The best!
