Have always been meaning to try a Shake Shack, as they're listed as gluten-free. It was early in the day and I finally stopped into one by my house. No one else there, as way before lunch time. I asked if they had a gluten-free menu, and I was just directed to look at the board. Other than the board saying there was gluten-free buns, it did not distinguish anything else as gf. Tried to use their static tablet to see what was available for me to order that was gluten free. Was too confusing and not easy to use. Left without ordering anything. On my way out, I explained that it was too confusing to know what to order, and the person behind the counter didn't seem to care. Unfortunately, will not go back.
Most Shake Shack locations offer gluten-free buns for burgers. A lettuce wrap is also an option.
They use a separate space to prepare the gluten free burgers. You get gluten free buns. When you put your order in the kiosk you can label what allergies you have. A manager came out to tell me that they can’t guarantee the fries are gf because they cycle the oil sometimes.
Located in Terminal C, take a right (towards gates C23-36). Was able to order a cheeseburger with a GF bun (pretty thin but did not fall apart!). They entered it as a gluten allergy and I asked them to change their gloves. The bun is toasted separately on the grill instead of in the toaster oven. I did not feel overly safe, but thankfully did not get sick. Nothing too special but nice to have an option in the airport.
