This is a real gem. Situated in the newspapers and magazines section of this posh supermarket near St Katharine Docks, very close to the Tower of London. The things with this payphone is that it rings really very loud, in the busy store you'll get an answer sooner rather than later. The panoramic shot attached gives you a good feel for the area.
