London: What to watch by night?

It's been a while since I wrote a London post (actually more than a month), but here is finally a new one. Of course there is clubbing, and going out for a musical or a bite at a restaurant at night in London, but that is not what I wanted to talk about actually during this blog. At one point during my internship one of my co-workers and I received free tickets for one of the bus tours and we did that at the end of the afternoon. We had planned to do it much earlier, but due to work circumstances it was late afternoon by the time we hopped on and that being in March, darkness set in quickly. What we saw wasn't what we had expected, as we had expected to see not much at all, but let me tell you this Westminster Pier by night is even more gorgeous than it already is by daytime. I get that it is a little more difficult to catch this sight now that it daylight is staying around longer, but if you get the chance to see it, definately do visit.
