Taqueria El Castillito in the heart of the Tenderloin serves up some of the tastiest burritos this side of town. When it comes to sides, return customers rave about the flavorful and fluffy rice, as well as the black, pinto, and refried beans. The pollo asada, lingua, al pastor, and carnitas are all top notch, and one would be hard pressed to not enjoy a dish featuring any of these meats. The generous sized burritos can easily carry over to two meals for those of moderate appetites. Fresh made aguas frescas refresh the thirsty with flavors such as watermelon and cantaloupe.
