London, St. Pauls and Cheapside

Update: we came on a train to London, and it's very similar to New York, but nicer somehow. The apartment that we're staying in is right above an Italian restaurant, so in the stairwell it always smells like really yummy pizza, which is considerably better then in New York where it always smelled a bit like cigarette smoke.
Yesterday we went to visit st. Paul's cathedral, in all its splendor. Pretty big. Very impressive. We got in pretty far for free, because there was some church event going on.
As well as the fancy st. Paul's, we visited under Blackfrair's bridge. This is a bit more interesting if you've read the Jacky Faber books. Anyway, it still wasn't super amazing, it just looked like a concrete path under some metal girders. Obviously, this wasn't the original bridge.
On the way to all these places, we walked down some very narrow roads, mostly in Cheapside area. You could step across the road as if it was a creek. Most of them were probably built a long time ago, wide enough for one man (or women) on horseback. Also got tube (London Underground) passes for the whole family today. I can't figure out how to end this post, so I'll just stop.
