McDonald's franchise owner Lou Groen invented the Filet-O-Fish sandwich here in 1962, after losing business during Lent in his market area, which had a lot of Catholics who skipped red meat during Lent. The story is well documented on the Web. I got the address by looking at http://www.smithsonianmag.com/arts-culture/the-fishy-history-of-the-mcdonalds-filet-o-fish-sandwich-2912/ for the store # (the location is blurry), and then finding the location at http://www.city-data.com/locations/McDonalds/Cincinnati-Ohio-2.html.
