My wife has Celiac and we've eaten here on a regular basis (twice per month, both done-in & take-out) without her getting sick.
They have a solid selection of GF menu options, and several are very tasty. Our favorite is the Chang's spicy chicken with GF egg-drop soup.
Staff knowledge of GF/Celiac can be spotty, but if you ask the right questions & emphasize the importance, they get it right.
