I let the cashier know that it was my first time, and we needed to do gluten free, and she helped us choose burgers. I asked for the GF bun, then saw the caramel apple “pie” shake. I asked it that would be okay for gluten free, and she didn’t know. I asked if they could just leave out any crust stuff and she said sure. The shake came with crust sprinkled on top, and my boyfriend’s burger came with the regular bun.
