We went here as a group with my son that has celiac. We felt safe and he didn't get sick. As the lady said, 95% of their menu is gluten free, which greatly reduces the risk of cross contamination. Pretty much the only thing with gluten is the flour tortilla shells.
There is a good variety of gluten free options. We had the family meal, which is a whole rotisserie chicken, a kids chicken taco (soft corn shell), two different bowls, and a salad, all gluten free.
They have some gluten free adult beverage options as well.
If you are looking for a place that's safe, casual, and tasty, I recommend Pollo Guapo.
