When your author visited last night, as he often does on a Thursday, there was a choice of tables, and the pool table was free, despite this being a thoroughly Central London pub, a stones throw from a huge railway station, on St Patrick's Day. That is its beauty.
Amongst some staff from Christian Aid, across the road, the pub is known affectionately as "the old man's", because it lacks the try-hard atmosphere of other local pubs. For here, rather than cocktails and loud music, there are ales, walls adorned with pictures of the neighbourhood in days gone by, and postcard scenes of long-dead locals on coach trips to the seaside. Your author likes it that way.
Whilst it was nothing gastronomic, and its readiness is announced with a 'ping', there was also cheap food available from Tracey's Kitchen, in the back bar. For more on the Duke of Sussex, see http://www.fancyapint.com/pubs/pub1231.php
