Edit! Sept 2023:
They have a separate fryer for gluten free now! They are also super good about cross contamination. Had the sesame chicken and it was so good!
Original Review:
Teriyaki sauce is gluten free, never have had an issue. Note that they have a shared fryer, so things that are fried but say GF, aren’t safe for allergies.
— Very
— Gluten-free items are marked on the main menu
