Get off at the War Memorial and cut across the corner of Wimbledon Common to The Hand in Hand perhaps? It's a Young's house so the ale choice is a bit limited, although last time I was in there the landlord had got on every ale that he could - 8 in all. And it did make the CAMRA S West finals, beaten by The Traf of course, because it is a good pub. He has a no children policy, no pop music, no one armed bandits, etc. Could do worse. There may be other good pubs on the route, but they don't spring to mind.
