The 1960s were early days for McDonald’s and Groen was struggling to make ends meet. So he cast around for a new idea, and spotted that another restaurant was pulling his missing Catholic customers in selling fish.
So he put some fried fish in a bun, added cheese and tartar sauce and put it on the menu…By 1965 the Filet-O-Fish had a permanent place on the McDonald’s menu.
I can attest that it’s something that got me through several Lents while at Texas A&M University. It didn’t hurt that the McDonalds was across the street from the Zachry Engineering Centre, where I spent much of my time studying for my Mechanical Engineering degree.
