The staff are happy to accommodate with a gluten-free bun, and always ask if they should take allergy precautions.
The gluten free bun is one of the best I’ve had. Nothing like the usual dry and icky ones that I’m used to finding in stores.
If you ask them to take precautions, they will serve you the bun in a separate, sealed package from the burger bits.
