Can be safe with a little caution, given that Thai cuisine is mostly GF. The wait staffs' gluten knowledge seemed to revolve around soy sauce alone.
Labels on the menu are ambiguous. Some things are marked gluten free, while others aren't despite listing no gluten ingredients. Had the Pad Thai (not marked GF) with whatever modifications they made, felt fine after.
