Before there was the La Luz del Dia restaurant, there was a La Luz del Dia grocery store, established in 1915 just a few blocks down on Main Street where the 101 freeway is today. It relocated to several places along Main Street including right next to the Plaza Church, North Spring Street, and in 1966 the Sepulveda House. Since 1941, the grocery store, then owned by Jack Berber, was a supplier to Christine Sterling, the founder of Olvera Street, when she lived in the historic Avila Adobe. Because of this long relationship, Ms. Sterling always insisted that Jack Berber should open a business directly on Olvera Street. On September 16, 1959, this opportunity turned into a reality and Jack along with his cousin Pancho Cazares opened La Luz del Dia Restaurant.
