The Chocolate Lounge has indeed closed down. The Rye Hotel does seem to be popular with local sapphists and in any case is just really nice - I can't vouch for anywhere else as that's the only local pub I seem to go to these days. In the past I've made new friends (ahem) in Dulwich Library and dog-walking on Peckham Rye, but if you don't like books or dogs then that's probably not much help. ED is an oddity in that it is positively heaving with lesbians, but without ever having had any particular bars/pubs/W.I. meetings as a social focus.
