Not great for gluten-free sadly. The meatballs contain bread crumbs so you are basically limited to just the steak. Decided not to give it a go.
As the previous rater mentioned, they didn't have a dedicated GF menu, but were very knowledgable. The head host took me under her wing, and outlined everything that was okay. I had the grape leaves (sans the lemon sauce, it had flour) and beets with yogurt sauce. Both were excellent. No GF beers, and steer clear of anything on the grill.
I didn't end up eating here but when I asked the host if they had a gf menu he said they did not but did point out items on the menu that were gf. He was pretty knowledgeable.
