Jesus, there used to be Swing on Petburi somewhere, then Bossy, Spicy. Back in the day Sin on Nana, a <deleted> ton of place in the building at the mouth of Soi 1.
I remember a cop gave me his gun in some place on Petburi at about 4 am. Drugs were involved
Back early early days (96ish) there was Silom Soi 4 with Deeper, (later DP 2000) the first real techno club in town, closed due to overdose and the space never reopened. Tapas was also on SoI 4. Then later on there was funky dojo on Patpong.
I have forgotten way more than I remember I suspect.
