One of the most iconic sights in London is the big corner neon on Piccadilly Circus. In the old days, it used to show some permanent logos, Sony and TDK I think. Now, it is an ugly, hi tech display changing every few seconds. But I digress...
Since my first visit there nearly 30 years ago, I have found the elegant curves of Regent street much more interesting than the Piccadilly Circus itself. If anything, Regent street looks even better at night.
