They had gluten free buns but I did not feel they understood cross contamination. The menu lists their fries as a gluten free option, but I was told it is a shared frier. They thought the gluten just cooks off making it ok.

I do not recommend Zio's as a gluten free option. they are not able to answer questions about salad dressings. also, I got sick after eating there.
