I ordered a burger and ice cream. The girl behind the counter assured me the burger would be prepared in a safe place way - that gloves would be changed before handling. I was also assured that all ice cream was gluten free. Well, something was not gluten free. I got sick immediately. The food was great, for sure, but if you are celiac, I highly recommend eating somewhere else. (I would give this zero stars if the app would allow it.)
Had a GF burger with bun. Nice to have this option in Yellowstone. Standard fast food fare with fruit options.
