I had prime rib (no au jus) and Bard's beer and both were fantastic. No cross contamination. Great place. Eager to return. Only the dishes paired with GF sides have a GF mark, so there are many more options than it may seem. Ask the server.
Update: I got very sick the last time I went. Everything tasted good but felt terrible later. I've eaten here four times, so one out of four glutened me.
