I always go here (and to other fatburgers) for a burger. They have a lettuce wrapped option and I’ve only felt a bit cross contaminated once.
The fries aren’t dedicated gluten free but when I’ve had a few in the past I’m usually okay.
The staff are really nice about being careful with cross contamination just make sure to tell them.
Online they have a gluten free menu available which is nice for thinking about your order ahead of time.
