London has a lot of postal districts. Just taking the London-specific ones (W, NW, N, E, SE, SW, EC and WC), there are 119. And most of these have a good range of pubs, too, though most obviously cluster in the centre of town. Not SE21, though: this postal district we can cover quickly. I now have photos of all three (that’s 3) of its pubs (though there’s one additional former pub still standing).
