Mackinaw City / Mackinac Island KOA Journey

Trying to locate a place that may or may not exist from my childhood. We camped at MillCreek campground (I think, could have been KOA dad doesn't remember, and grandma has since passed). But there was a food spot (or restaurant) nearby where you could "fish for your lunch" I want to say it was trout or maybe catfish. Anyone have any suggestions on what or where that might have been? Maybe it closed up its doors.. Maybe it's in a different city or state altogether, lol.. Thankyou for helping me piece together a puzzle 25 years ago lol....
