The main thing is that they have a GF bun option for their burger. Their menu is pretty straightforward and the employee working the register is knowledgeable enough to answer your questions.
They have a lot of burgers options that can be changed to gluten-free. The bun is fairly good, not too dry, and the rest of the burger makes up for that. I usually pair it with a shake instead of the fries (which are not GF!)
The fries do not have a dedicated fryer and I think may even be beer-battered. Which is sad because they’re SO good! Their burgers are excellent enough that it makes up for it. I haven’t gotten sick eating there!
