They have yogurt, many are labeled gluten free. Sadly the toppings are not.
All of the yogurts are marked for allergens including gluten and the quality and pricing are both great. The downside is that the toppings selection is basically off-limits to people needing GF food due to the brownies and cookie dough sitting right next to everything else. I picked out a few fresh strawberry slices once and was glutened.
Many gluten free frozen yogurts and toppings, they have each flavor clearly marked with gluten free, dairy free, or sugar free etc. Wonderful!
