They have gluten free cones and their fries are fried in a dedicated fryer! The staff will change their gloves/get a clean scoop to scoop your ice cream if you ask them. Allergens for their flavors aren’t listed in store, but they are listed on their online ordering.
I tend to order ice cream that hasn’t been scooped prior to my order very much, to try and avoid cross contamination from prior orders, but the staff does rinse the scoops between orders so I might just be paranoid.
