Well, the order was suuuuuper mixed up and considering one item was ordered on a gluten free bun, that's really not good. It looked like everybody's sandwich had a little bit of everybody else's sandwich on them. One person ordered a bacon avo, one person ordered a double with cherry peppers on a gluten free bun, I ordered my usual, the vegetarian mushroom burger. When we got them, they all had cherry peppers, two had bacon and my bun had bits of burger meat stuck to it. We are big Shake Shack people and the gluten issue is a sensitivity and not an allergy, so it wasn't a problem for us. Would not recommend for people who get very sick if they eat gluten.
