I've had Frozen Yogurt from this place a number of times and have not had a reaction. They have staff who are very knowledgeable about cross contamination and they are very cautious. If you play it safe and stick with just the yogurt or sorbet selections they are clearly marked with a gluten free symbol. And if you request fresh toppings they are willing to grab some uncontaminated ones from the back within reason. I would avoid busy times to avoid any slip ups but overall a great time.
