'When a man is tired of London, he is tired of life' said Samuel Johnson. Well, if you think you know London and have seen all the big sights let me show you the stranger side of the capital. A great tour for frequent visitors to London or locals who think they already know it well. We'll zig zag around, stopping at some things you would normally walk right past. Steps that lead nowhere, a lamp fed by an unusual sustainable bio fuel, a door that might fool some people and the sign for a very bizarrely named alley. Let's scratch our heads about old Imperial measurements and smile at the somewhat idiosyncratic pedestrian crossing lights. Certainly plenty to smile and wonder about!
