Question: In which Ohio city was the McDonald’s Filet-o-Fish invented?

Answer: The Filet-o-Fish was invented in Cincinnati in 1962 by McDonald’s franchisee Lou Groen. His restaurant was located in a predominantly Catholic neighborhood, and he noticed sales declining on Fridays during Lent. This observation inspired him to create the whitefish sandwich we know today as the Filet-o-Fish.
