In a move to focus more on growing the Jack in the Box Brand, the San Diego-based company is also mulling selling Del Taco.

The locally-owned fast food chain opened the nation’s first drive-through hamburger outlet in 1951 at 6270 El Cajon Blvd. in San Diego (photo, left). Soon after, Jack in the Box outlets popped up across San Diego and East County locations such as La Mesa and El Cajon, ultimately going national.

Jack in the Box, the San Diego-based fast food chain offering burgers, chicken and more, announced plans to close 150 to 200 stores.
