Without the kick to qualify as hot sauce, the tomato-based, sugary-yet-smoky topping that is the staple flavor of this decades-old gringo taco joint is simply “taco sauce,” given in generous handfuls of packets with every order and even sold separately for the condiment's numerous cult followers. Taco Lita, the retro stand, is a slice of Americana: bright colors, cheerful servers, a no-frills menu with greasy combo burritos, and rumors of a ghost that haunts the men's restroom. This spot isn't for al Past whores, so don't try ordering it — refried beans and shredded cheddar can be found in virtually all menu items, which can and should be doused with their signature sauce, so addictive you will find yourself hoarding the packets in a jar at home, and returning for more on your next calorie binge. 120 E. Duarte Road, Arcadia. (626) 445-2889.
