London's bridges

The Tate Modern art gallery is the best place for lunch in London: seven floors above the Thames, looking down on the Millenium Bridge that was destroyed so spectacularly in the latest Harry Potter movie, across the brown waters of the Thames to St Paul's, amazingly big, and the remarkably unlikely-looking Gherkin. It's a great setting to enjoy Cornish mackerel, Victoria plums and fizzy elderflower presse.

Along the river is the new Jubilee Bridge, the old Waterloo Bridge, and a wonderfully compact cluster of iconic sights that would be a cliche if they weren't actually the real thing.
