Taco Jalisco, 8645 Richmond Hwy, Alexandria, VA, 703-360-1253, Rt. 1, near Fort Belvoir. A reader recommends this as a good hole-in-the-wall place. I have yet to go. I believe there are other worthwhile places nearby.
Also recommended to me are
- El Charro, 2893 Dale Blvd., Dale City, VA, 703-680-0484
- La Jaibita, 8059 Centreville Road, Manassas, VA, 703-330-0577
- El Puerto, 7230 Richmond Hwy, Alexandria, VA, 703-768-7340
Caveat emptor, but do let me know what you think, I bet at least one of them is good.
