Although the thread is about Soi Twilight/Duangthawee/Pratuchai (looking back, for years it was called Duangthawee - only recently has it been changed to Pratuchai and I still don't know the reason!) Bangkok also had gay bars elsewhere. In Patpong 2 there used to be a host bar on the upper level. I wonder if anyone else remembers it. Was that Tiffany's? And then for a long time Silom Soi 4 had the famous Rome Club, Bangkok's best mixed disco with hordes of gay guys at the week-ends. For whatever reason, the owner decided that he wanted the gays out and thereafter made it a straight club. It died pretty soon after that to be replaced by Roxy. But it could never find the right formula and it too died.
My Way has been mentioned in other threads - a small bar with twinks just off Rama 4 between Silom and Suriwong. I don't remember there being shows but I reckon the boys were some of the best dancers in the gay go-go bars at that time. Along Sukhumvit off Soi 10 there was and, I believe, still remains Inter Mustache House. Most farang never got above the ground floor where 3 or 4 Thai guys would gyrate as though dancing. The real go-go bar was upstairs and was mostly patronised by Thais. Further along I was 3 or 4 times at another very small host bar just across from one of the entrances to the Ambassador Hotel car park, but I have no recollection of the name.
