I've only been to London once about three years ago for around 5 days, and I can undoubtedly say that London is one of my favourite capitals of Europe, along with Paris. I went to see all of the typical tourist stuff like Big Ben, The Eye of London, Tower Bridge, Greenwich and so on. I also got to see the musical "We Will Rock You" based on Queen's music, and shop like a madman on Oxford Street (especially Virgin Megastore - God, I love that shop!). It was a really great trip and I've been wanting to go back for quite some time now. I'm pretty sure it'll happen at one point.
