I have been here 3 or 4 times now and have not had a reaction, fingers crossed. They have great customer service. Let them know you have an allergy and they will "Red Flag" your order and change gloves. I've had the grilled chicken sandwich with gluten-free bun (I asked to assemble it myself) and the grilled nuggets. Chick Fil A sauce on the side. All beverages are gf.
