Jack in the Box at 1110 C Street in downtown San Diego operates a drive-through outpost of the chain founded in this city in 1951, when the first intercom-equipped ordering lane debuted on El Cajon Boulevard. The late-night taco and egg roll lineup draws from a Tex-Mex-meets-American formula distinct from the classic cold-cut construction at Cortez Hill Market & Deli up the hill. Breakfast croissant sandwiches, hash-brown platters, and loaded burritos roll through the drive-through window before dawn. The coffee and iced-drink menu runs hot drip, iced, and vanilla options — a simpler format than the single-origin roasts at Achilles Coffee Roasters @ The Rey but built for speed. The Ultimate Cheeseburger — two beef patties, American and Swiss cheese, mayo, ketchup, and mustard stacked between three bun layers — is the most structurally complex burger on the menu.
