The last time I went (a couple of years ago) they did not have a beer or wine license but if you asked for wine, they served you a glass on the house. Nothing special, but that was very nice of them. The folks who run that place are really nice.
I was there last month for the first time. I consider it a place I'd take others too, and I didn't even know about the wine problem, they had a house wine I enjoyed, and I don't recall the price being too painful. Owner is obviously present a lot.
