As others have already mentioned, this restaurant isn't completely GF. They have flour tortillas.
However, I showed the waitress my Gluten Free Adventures celiac travel card and she understood my needs.
After my second visit, I was able to confirm that the fryer is dedicated gluten free. So, nachos and hard shell tacos are fair game.
The food was very tasty and I didn't feel sick afterwards.
