My partner and I ate dinner there on a Saturday night. We were in Picton for the weekend and tried to get a reservation that morning but were told they were booked -- but to our surprise the restaurant called me back about an hour later to say they had a cancellation if we were still interested.
So we went for a late dinner, and enjoyed it. The restaurant is nice, the service was good, and the food was terrific (she had the lamb shank, I had the prime rib.) We would love to get back there in the nicer weather as it looks like a lovely setting for a summer meal.
