Jack in the Box in Coronado operates at 3238 Guadalcanal Road, Building 33, inside Naval Base Coronado's amphibious base perimeter — one of the only drive-through fast-food options on the military installation in the 92118. The location shares on-base dining traffic with Dunkin' at the nearby Navy Exchange, serving active-duty, dependent, and civilian personnel with base-gate access through NASNI. The full Jack in the Box menu runs all day — burgers, tacos, egg rolls, curly fries, chicken sandwiches, and breakfast builds including the Sourdough Jack and Ultimate Cheeseburger — a format the San Diego-founded chain has operated since 1951 when the first location opened in the city. Jack in the Box's all-day breakfast availability fills an on-base gap for shift workers and late-schedule personnel, paralleling the evening pub-food service at Danny's Palm Bar & Grill off base on Orange Avenue. The chain's headquarters remain in San Diego at 9357 Spectrum Center Boulevard, making the Coronado base location one of the closest franchise outposts to the corporate campus that oversees 2,200-plus restaurants across 21 states.
