I go here regularly (way too regularly) and have never been glutened. I still remind them every time that I am celiac, and they've always taken care of me, even at busy happy hour. For the reviewer who didn't stay after he saw "flour flying everywhere", I'm not sure where he was. It's an open kitchen and I've never seen flour even in use.
The place is very small and has no where to wait. It was awkward being hit by the door and obviously annoyed thé host that I was standing there, so I went to the bar by the kitchen. I saw flour flying everywhere and an open grill, so we left. Was not worth risking cross contamination before a flight.
Although they do not have a gluten free menu, the menu clearly indicates which items are gluten free. They have a dedicated fryer for fries and chicken wings. I had a stuffed portobello on a gluten free bun, and it was delicious. The server was very knowledgeable. I will definitely go back.
