For anyone around Tower Bridge and the Tower of London it is a must to visit St Katherine's Docks which is a 2 min walk from  Tower Bridge, next to the Guoman Hotel. A little hidden secret, very picturesque and with lots of charm. The docks are linked to the Thames by small pedestrian bridges and the cobled streets,  boats and traditional architecture ( like the Dicken's inn) makes you feel you are suddenly transported to  another time. It holds a food market on fridays for lunchtime. There is a variety of international flavours to choose from away from the busy turist spots and at really good prices.
