Still waiting to hear from Edwardian Tearooms restaurant manager, but I have been out all day (you'd be impresssed, jeni - got DH back to shop again to order new suit as they no longer do the fabric of his last suit to get new pair of trousers) also out to lunch for our wedding anniversary. However, I am confident I can get a response before next week so will then present options so far and ask you to choose. I take your point about shutting at 4 , crimson, (we could always move on elsewhere for tea....... and more talking!)
I don't think Strada will want a deposit and I won't offer (!) because I know how easily the best laid plans of mice and grans gang aft agley.
