El Taco, one of the best-kept secrets in Manassas, serves Tex-Mex comfort food that can't be beat for price. The menu is small and hasn't substantially changed since the resturant was opened in 1970. The dining room is funky, with tiled floors and glowing stars hanging from the rafters, and no wait staff. Just place your order at the window and pick it up when your number is called.
