They said they could mix my ice cream in a separate container (not on the shared cold slab), which was good to know. However some of the ice creams themselves contain gluten, like cake batter and oreo filling. I saw some oreo crumbs in the gaps between ice cream bins which was worrisome. And they only rinse the scoopers, which makes me think cross contamination could be an issue unless you ask them to get a fresh one.
There are plenty of gluten free ice creams, but not that many GF toppings I felt safe getting (and that I liked). I also asked whether the sprinkles were GF, and nobody in the store knew, therefore I ended up getting no mix ins just to be safe.
