Yep, agree. Way Out is definitely the place to go. My favourite club for many years. Never had a bad night out there. Always great fun and totally relaxed. No grief. Decent music. A very liberal attitude. If you go please pass on my regards to Regine, Krissy & Sonya (all gorgeous!).
If you want to try a bit more of a swingers club for T-Girls then you could also try Stunners near Limehouse Basin. Try Googling it. A bit of a wild place with a variety of "theme rooms" - including the totally blacked out room where you haven't a clue who is who...
