Love the options at this place and so far so good (aka have not got glutened). Must say that the person out front changes around so it really depends on their familiarity with CC and food handling protocols (since they warn the kitchen).
EDIT Nov 2022: they now have separate fryers for gluten vs non gluten foods. The last couple of times I visited, the kitchen is very much knowledgeable now and so are the staffers out front.
