How a Cincinnati Businessman Created McDonald’s Filet-O-Fish Sandwich for His Catholic Customers During Lent

Lent and seafood go hand in fin.

And McDonald’s Filet-O-Fish, a 54-year fixture, is one of the most popular menu items, especially on the Fridays leading up to Easter, a time when many Catholics forgo meat.
