Only available food was GF sugar cookies, on a tray underneath gluten baked goods. I think they usually have 3 other cookie flavors as well. Storing GF food above gluten food is such a basic cross-contamination precaution, so I didn't risk ordering.
If you're not Celiac, you'd probably be fine. Not recommended for those sensitive to cross contamination.
