London probably has good food, but as you say its less about British food. I think the highest expression of British food is in (what I understand to be) the vastly depleting countryside of England, the place that gave us Berkshire hogs, and vegetables grown with an inordinate amount of pride. British country cooking is simple, but elegant in its simplicity, I think. Give me a pork and apple pie over any silly pretentious continental dish drowned in some sort of something-aise sauce, any day!
