The Voltaire Street outpost of Roberto's Taco Shop occupies 4770 Voltaire as the OB representative of the San Diego chain that began in 1964 as a San Ysidro tortilleria and is widely credited with introducing the California burrito to local taco menus. This location runs a drive-through window that serves the Sports Arena and Point Loma commute, with extended late-night kitchen service Friday and Saturday into early-morning hours that the surrounding bar corridor does not match — including last-call traffic walking down from Sunshine Company Saloon on Newport Avenue. Carne asada, al pastor, carnitas, machaca, and rolled-taco plates run off the standard Roberto's line, with breakfast burritos available from the early-morning shift forward. The drive-through and counter together absorb the post-bar surge and the morning surf-camp burrito buy heading toward Sunset Cliffs. Outdoor seating sits adjacent to the parking pad, sharing the Voltaire dining ecosystem with neighborhood Mexican operator Hugo's Cocina closer to the beach side. Bulk carne asada and California-burrito orders for OB Street Fair vendor staffing, surf contests, and Robb Field tournaments are produced from the line that runs continuously through the chain's signature extended-hour schedule.
