Thanks for all the good suggestions. I've put all of them in my files for future use. We're going to eat at The Cinnamon Club. During this month of January, they have a fairly reasonable prix fixe dinner and lunch so it seemed a good time to try this lovely spot.
If anyone is interested, the details are on

Re:Sainsbury's... it's my local supermarket. Their prepared Peking duck dinner with pancakes is something I never found in the States! I prefer Waitrose, but that's the pricey spread. :-)
