Many of their hand-scooped flavors are gluten free. Be aware that they normally use the same scoops for gluteny and gluten free flavors, but the staff was very accomodating when I asked for them to take my yogurt from a new container in the back and use a clean scoop. Keep in mind that if you ask for yogurt from a new container, you may have to wait for it to defrost a bit for them to be able to scoop it, since it's coming out of the deep freeze, so make sure you're not in a big hurry. The best frozen yogurt ever! I had mocha almond, delicious!
Nearly all of their frozen yogurt is gluten free. I've been twice and both times they could tell me immediately what was GF. They also volunteered which machines most recently had a different flavor saying that they cleaned in between but said I avoid those to be extra cautious.
I'd eaten here before - JUST the soft serve with no added toppings. I ate here last Sunday and got only GF-labeled ice creams. Plus the caramel & chocolate syrups (each in its own container) after verifying with the worker that they were GF (according to their allergen notebook). I don't know whether an ice cream machine was cross-contaminated or if it was the syrup, but I hurt worse than I had since being hospitalized 2 years ago (when I was diagnosed with gluten sensitivity).
They have 12 different flavor selections, and they are ALL gluten free!
