JACK

Jack in the Box Inc.

A fast-food chain that runs drive-through restaurants across the United States, serving burgers, tacos, and its signature curly fries. It began in San Diego in 1951 when restaurant owner Robert O. Peterson installed a two-way intercom so drivers could order from their cars, and the name came from the jack-in-the-box that popped up with orders. The company also once owned the Qdoba Mexican Grill chain and is known for its round-headed mascot named Jack.
