The Bearded Frog

They have a few options on their menu that are specifically marked gluten free. Expensive, but good food. Would definitely go back.

Celiac friendly?

Yes

They don't have a gluten free menu but they were very accommodating. I told the server I couldn't have gluten or dairy and they were happy to suggest options or leave things out or make substitutions. I had the duck and it was delicious. The menu is small in general so I didn't have a huge selection, but the dairy was really the bigger issue. I overall I was quite happy.
