Two not mentioned - Dulwich and Sydenham and Chislehurst. Don't know much about D & S although there is a member on this Forum and Chislehurst is OK but at about 5100yds with 7 par 3's it is rather "compact" and a hard hat is recommended with all the crossing holes.
Chislehurst was the closest private club to home when I was a boy (Royal Magpie was the closest course), and the Uncle that introduced me & encouraged me was a member there (and at Littlestone, hence my love of links golf, but that's for another day), so I may be a little biased, but I enjoy Chislehurst. Compact is a fair description but I feel it makes the most of the land it has. It's tight, but I don't remember that many crossing holes (1st & 15th?). The par 3's are very varied and the clubhouse is lovely. No idea on the social side, but I enjoyed my rounds there, with or without Uncle Harry.
and I must put High elms on the list for a return visit next year, it is a nice layout and another I played regularly as a lad.
