It all started back in 1974 in San Diego, CA when a man named David Ruiz opened Cotijas Taco Shop. After experiencing some success with the business, David helped his brother Javier open his own franchise in El Cajon city. Javier passed the taco legacy down to his son, Javier Jr., who moved with his brothers to Phoenix, AZ, where they opened 3 taco shops. Several years later, the Ruiz brothers decided to look around for a more serene place to call home, and they settled in the peaceful town of Columbia, TN, where they opened Taco Express. Their Tennessee taco franchise eventually expanded to the cities of Spring Hill and Franklin. The franchise was ultimately renamed to Oscar's taco shop. CALI Burrito came into existence when Adrian Ruiz decided to continue his family's legacy of serving customers authentic Mexican cuisine by opening his own separate franchise in Spring Hill, TN.
