Thanks for sharing your feedback - we very much appreciate you bringing this to our attention! We do our best to provide an ample selection of gluten-free menu items for our guests, and we sincerely regret the error we made by listing our fresh potato chips as a gluten-free item. This item will be removed from the gluten-free section with our next menu reprint, so the error will be corrected by February 6.
On the flip side, we're glad to hear that our manager was able to confirm that the chips were not gluten free before you ordered them. All of our managers complete an allergen training program so that they're able help when a guest has questions about the menu.
Lastly, you mentioned that you didn't try the gluten-free bun. Next time you're in, I'd encourage you to give it a try - we've received great feedback from other guests, saying that the texture and consistency are much better than other gluten-free breads they've tried.
In any case, if you have any other feedback that you'd like to share with us, please don't hesitate to do so.
