This place was great and the staff was very accommodating! Since they roll-up the ice cream they cleaned one of the pans thoroughly and then made mine. The ice cream base is just plain (or nonfat yogurt or vegan) and then you add insides and toppings. It’s pretty much known was is GF and what isn’t as far as the additives go. And lastly, you have to expect the line is often going to be long because it’s specialty ice cream.
