Throughout the years I have had Celiac, I have always been able to eat Shake Shack. They can make the Shack burgers gluten free as long as you ask them to make it on a gluten free bun and specify gluten and/or wheat allergies. I have eaten there countless times and have never gotten sick. I got the ShackBurger double patty with pickles. (The other food in the picture is not gluten free, as it is not mine)
