London in a sentence: "London is a city by a river, plus lots of villages joined up by an underground railway." - @TubeRambler
Last month when I was back in Canada, one of my oldest friends said in all seriousness: "What is there to do in London anyway?" As the video above shows, pretty much nothing.
'It's Got To Be London' was shot by Tim Benzie and Paul Joseph who are trying to convince their niece and her boyfriend to come to London instead of taking a cruise (as if that's really an option). To be honest the last thing London needs is more tourists in the summer. (With apologies to my family members who will be doing exactly that)
Nevertheless, if you're trying to convince someone to come here versus anywhere else in the world try sending them this video. You can find out more about the whole project from their website: http://www.itsgottobelondon.com.
