Who hasn’t heard of Jack in the Box? Most of us have grabbed a burger or taco there at some point. But did you know it’s been serving up tasty bites since February 21, 1951? It all began right here in San Diego, back when the drive-through concept wasn’t even a thing yet.
Jack in the Box, a San Diego legend
On that historic day in 1951, local businessman Robert O. Peterson opened the very first Jack in the Box at 6270 El Cajon Boulevard. While carhop drive-ins were already popular at the time, Peterson’s new concept was completely revolutionary. Jack in the Box became the first major restaurant chain to focus primarily on drive-through service. How? By pioneering the use of a 2-way intercom system.
Before this innovation, customers had to pull up to the window just to speak to the cook. The intercom allowed one driver to place an order while the car ahead picked up its food. This simple change drastically sped up service times, creating the blueprint for the modern drive-thru experience we all know and love today.
Complete with a giant (and iconic) clown head on the roof, that little hamburger stand on El Cajon Boulevard changed the fast-food industry forever.
