I've been here many times, always for takeout. Although, they do have a cute restaurant area for eating in, as well as live entertainment (weekends I think). They know how to handle GF and will confirm GF items when bringing items out to you. It's not dedicated GF, so you have to go over things with them, but they seem to get it.
