Where's the world's best food?:
The Guardian lists the best 50 foods to eat and where to get them. I've had a few of these (ravioli at Babbo, pork at Gramercy, pho at Pho 24, pastrami at Katz's, etc.) but, sucker that I am for such things, I particularly enjoyed reading about the Turkish olive oil available at an electrical supply shop in London.
