Even if its under maintenance, you can't resist a selfie with Big Ben and the Houses of Parliament. You can get a great shot from the opposite side of the river.

Come around 11am for a chance to catch the Changing of the Guard. You might have to queue to get one of the best views so get there early. 

A local ale, in front of a roaring fire, on a cold winter night = bliss

The bridge opens up around 3 times a day.

You'll find plenty of interesting graffiti right across East London and Shoreditch.
