Taco stands, Night Clubs, and Gift Shops all operated by Mexicans in their colorful native cosutmes.
–The street originally connected to the city Plaza that formed the center of Los Angeles civic activity in the mid-1900s. It was renamed in 1877 to honor Augustín Olvera, the first Superior Court Judge of Los Angeles County.
