They have a chart on the wall that shows you all the gluten free flavors. It was the best experience I have ever had in an ice cream shop.
This store is actually now on Amsterdam ave and 85th street. Listed gluten free ice cream flavors. My only issue is that the toppings are "do it yourself" and so many parents let their too young children spill peanuts and cookies all over the other topping. I hate those kind of parents >:( fruit is separated in front. You should ask them to separate gf items from non gluten free when you go there. The more ppl that ask, the more likely it is to change.
Only a few flavors are not gluten-free
