Afaik there are no agricultural fields surrounding London nor there is any fresh see-food to speak of. I've visited London only once 10 years ago but I don't remember any fishermen bringing their catch in the morning in downtown London and I'm pretty sure things have not changed since then.
Later edit: Please do substantiate your point in what you think makes London food great, with some examples, maybe I've been living in the dark all this time in thinking that a place that glorifies "fish and chips" cannot be the "culinary capital of Europe".
