My starter, a brawn and ham hock terrine, was less inspired -- and, in my unlettered opinion, should have had the mustardy stuff on one side (not drizzled over the top) -- but the puddings more than made up for it: both the chocolate tart and the Muscat caramel cream were delightful.
Guest ale was pretty nice too, I thought, but I don't actually know a good ale from a hole in the ground, so YMMV.
You can book and you probably should, although it didn't quite fill up while we were there.
