Pretty good. Not a dedicated gf restaurant, but the food is yummy. Know that the gf menu is slightly old. I had steak fries with my burger (no gf bun, just wrapped). And the fries are all fried in the same fryer, so there is cross contamination. All in all it was good!
As far as restaurants go, The Kettle does okay. They don't offer any gluten-free substitutes, like gluten-free bread or muffins. But they do have a gluten-free menu, and my server was knowledgeable about gluten allergies and avoiding cross contamination. They offer breakfast all day, so there were extra choices of naturally gluten-free foods.
