I only first visited Bangkok / Soi Twilight in 2015, however I also find the history of the scene very interesting (being in my early 30's on that first visit meant I wasn't fortunate enough to experience the 'old scene'). I still haven't visited the new scene in Patpong, as most of my subsequent visits have been straight to Pattaya / Cambodia / other SEA countries. But the new Twilight is definitely on my list once travel is finally practical again!!
