This place does not have a dedicated fryer. The truffle fries that are labeled gluten free have malt vinegar in the description. The chef and server didnt recommend celiacs eat there as they do not have a big cooking/preparing space and boat loads of wheat in the area.
Great place for a quick bite if you are staying in the City Flats hotel or just walking near-by. Their GF options are mostly in the small plates section but there are plenty! The staff is knowledgeable and they will take care of you. I had the pork tacos and they were excellent.
