I am not convinced that the pancake house is part of the "Original Pancake House" family. Although the jumping chef character pictured is reminiscent of the standing chef character used by the chain, in doing some simple research online, it appears that the standing chef logo we see for the chain today is pretty much how it has always been.

This unconvincing logo research aside, the restaurant COULD ostensibly be an Original Pancake House. The chain was formed in 1956 in Portland, Oregon. However, I checked on Street View, and none of the current Michigan locations match.
