There has been some discussion about the exact location of a one-time tavern in San Mateo. The Black Egg, according to our records, existed in the early 1960s at the intersection of 16th Avenue and South B Street in the Hayward Park neighborhood. The old watering hole was almost adjacent to what was then a Southern Pacific Railroad commuter stop. Today, the site appears to be either closed down or part of a wellness outfit. It’s not entirely clear. The Black Egg persists in Peninsula lore because of a ghoul pool there which involved betting on when the next person would leap off the Golden Gate Bridge. Whoever came closest to that date would win the pool of cash. Supposedly, the beer hall’s owner wound up committing suicide off the fabled span, allowing his spouse or significant other to walk home with the dough.
