I can't do it the 29th because that is when we are doing Thanksgiving at our place so I have to run home and throw a turkey in the oven :/ Kay, would it be easier for you if we did it Saturday 6 December? That would give you some time to settle in too!
Also, if either of you can think of a small, comfortable place in West London, I can get there easily on a Saturday as I will be coming from Hyde Park. Alternatively, there is the Serpentine Cafe in Hyde Park that has loads of tables and a really nice view (although there is some winter fair going on now that may result in a lot of people now :/) I was at Timber Yard yesterday about 1.30 and it was heaving with people, and I can imagine Xmas shoppers will only make it worse in the coming weeks.
