Went with some friends, none of who have celiacs. They were very clear about what is and isn't gluten free, were confident in their answers. I ordered the philly on a GF bun and the sweet potato fries - the person taking our order warned me the sweet potato fries were tossed in cornstarch before frying s they might look coated but that the coating was GF.
Everything was delicious and I had no reaction or issues afterwards!
