This is an addictive puzzle from the Londonist blog - what London entity does each of the elements in the table represent? There's some patterns and relationships just like in the real periodic table - look at the comments on their page to get some ideas based on what others have cracked so far...

I bought a guitar here recently and it was a great experience - the guy who runs the place spent about 3 hours with me, helping me try out stuff and explaining all the voodoo etc. The place was filled with curios like 6 necked guitars and old valve amps that his dad had made back in the day. They still manufacture their own custom pedal effects that are sought after by today's rock and pop bands - Noel Gallagher had been in that week to order some of the pedals - hopefully prepping for his new solo venture? Excited.
