Most of the ice cream flavours are gluten free (though be sure to check- chocolate brownie isn't etc.) and they were very helpful/ considerate about my allergy. Very busy, popular place. Interesting unique flavours. They even offered to give me mine from a fresh barrel with a fresh ice cream scoop to avoid cross contamination. I didn't ask for this, but I think that means it would be celiac friendly if you needed it to be. Had it many times and always feel fine after.
They have a wide variety of gluten free flavors. You can easily find them listed on their webpage, along with dairy free options. I let them know that I had an allergy, so they cleaned off a section in the corner away from everything, changed their gloves, and scooped from a new container. I also asked them to get a container and spoon from the back, as the others are placed right by the cones.
Amazing IceCream! They have lots of unique flavors and they know which are safe and not safe for celiac disease. Probably the most impressive thing was since the tubs have cross contamination, the server opened small pints even just so I could try a flavor. I felt so safe and loved the ice cream
