Whether it's the religious roots, the secrecy surrounding its recipe, or the global impact, the Filet-O-Fish story is a fascinating blend of tradition, innovation, and cultural resonance. Over the years, the sandwich has undergone subtle changes, reflecting McDonald's commitment to staying relevant and appealing.
