Open around the clock at 1905 Garnet Ave in Pacific Beach, 92109, the Jack in the Box on Garnet is a fast-food restaurant that serves as the neighborhood's unofficial 24-hour kitchen. Jack in the Box was founded in San Diego in 1951, making it one of the few national fast-food chains that can genuinely claim local roots — the first drive-through location opened on El Cajon Boulevard, and the company's corporate headquarters remained in the San Diego area for decades. This Garnet Avenue outpost offers the full menu at all hours: Jumbo Jacks, Ultimate Cheeseburgers, Sourdough Jacks, two-taco value deals, egg rolls, chicken sandwiches, and a complete breakfast lineup available day and night. Craft beer fans heading to or from SD TapRoom just up the block often pass by the golden antenna ball on their way home. The drive-through handles the late-night bar crowd that pours off Garnet after last call, while daytime traffic skews toward families and solo diners looking for a quick, affordable meal. The San Diego County health department has scored the location at 99 out of 100, and the restaurant offers active military discounts. Delivery is available through multiple apps, and the parking lot provides enough space for the drive-through lane plus a handful of walk-in spots. Guests looking for a more upscale American dining experience on Garnet can visit Firehouse American Eatery & Lounge for craft cocktails and a seated dinner. The menu's range — burgers, chicken, tacos, breakfast, desserts, and late-night munchie meals — keeps this location relevant across every daypart in a neighborhood that rarely sleeps.
