With a multitude of choices for Mexican food in the Sparta, NC area, your best choice is Mis Arados. I LOVE this place, the service is always good, both the chips and the salsa taste like they are home made, and the fajitas are super yummy!
We also like the nacho fajitas, but rarely get them because the fajitas themselves are so good.
The only negative about this place is that they don't serve margarita's!
