Yes. I was in Fortnum and Mason yesterday. (They stock kilo bars of Valrhona, which is what I was after), and noticed that they were flogging white truffles at: £5700/kg. Blimey!

Gidleigh Park marmalade. It's a funny texture: being simultaneously runny and very coarsely-cut. But it tastes fantastic - not a note of unpleasant bitterness at all. But then again, marmalade's a bit like tea - the best is the one you make yourself. :-)

What they say. Sushi-Say is the place to go. The last time I was there, the bar was almsot entirely populated with chefs from Nobu. I would go for lunch on a Saturday or Sunday, where a set meal will set you back from 8-15 pounds. A decent meal in the evening will be about 30 quid, but booze is pricey. The couple who run it tend to visit their relatives in Japan in January, so if you're around early in February, you may get something esoteric off-menu. The home-made ice-cream is top-notch! (I lived in Willesden for 3 years and was there most weekends!)
