Detroit to Get Applebee's at 8 Mile and Woodward

[old guy]

ASR89 wins! Those are the three I was thinking of.

There's also a Big Boy on E Jefferson, but that's debatable as to whether that's a national chain.

Any we're missing? A pathetic number, for sure...

I'm reasonably certain that Big Boy could be considered a national chain.
By 1979 there were more than a thousand Big Boy restaurants in the U.S. and Canada.
