My kind daughter managed to show me the faceplant page. It turns out that the exhibition is on from Nov 7th to Nov12th. So if you want to see it, this weekend would be the time, but no good for us next weekend I'm afraid!
Back to plan B. I find Jimmy's and Flixton to be a little on the sleazy side! How about Kingfisher's favourite Café at the Hillcrest Nurseries on the B1111 between Stanton and Barningham?.. Nice and warm inside, lovely food and great service..
