I worked in Greek Street for many years, my 'local' was The Pillars Of Hercules, but I used to frequent many of the Soho pubs.
Not a big fan of the west end but loved Soho especially the transition from work time to evening, some of the characters that drank in those pubs were amazing and they...
Another vote for a walk along the riverside, some great pubs on both sides.
Or maybe go into Chiswick,close to Hammersmith, nice pubs at eateries in Chiswick.
