As someone who grew up in San Francisco, lived in Los Angeles, and who has explored the taco trails of California and Mexico, I thought I had tasted the pinnacle of taco perfection. Little did I know, my taco journey had merely scratched the surface. What I once considered the peak of taco excellence was, in reality, just the realm of good and great. It took a fateful business trip to CDMX to shatter my taco illusions and introduce me to an entirely new level of taco brilliance.
