Delicious! Order an allergen cup and they put on clean gloves and scoop it from a safe container from the back. Talk to the supervisor for allergy questions.
The cashier actually has a list of their flavor a that DO contain gluten (which is a smaller list than the gluten free flavors). When paying, ask for an allergy cup and tell them what flavor and they will have it specially made from a new container with clean scoops and gloves in the back. SO worth the extra few minutes wait! My daughter has Celiac and has not had an issue here on SEVERAL trips.
Cashier has a full list of their gf ice cream flavors and you can order it as an allergy cup or allergy shake and they will be extra careful and open a new one in back to make yours with a cup from the middle of the stack, clean spoon clean blender. Takes a little longer but always certain I won't get sick!
I always get plain chocolate ice cream, chocolate milk, and lemonade. I haven't asked about their flavors of ice cream that are gluten free, but I'm sure there are more options then just chocolate. Not sure if celiac friendly.
