Adhere the 13th is a narrow shophouse on Samsen Road, just past the canal from Khao San. The room is tiny: a bar in the back, high tables along the side, low chairs up front, and album covers plastered across every surface. The band sets up in the middle of the room, close enough that you walk through them to get to the bathroom. Blues and jazz every night, no cover charge, and the crowd is a mix of old-hand expats and locals who have been coming for years. The kind of place where the music starts and the street outside disappears.
The space barely holds twenty people indoors, and when the band is cooking, every seat is taken and the overflow spills onto plastic chairs on the pavement. The walls are covered in road signs, vinyl records, and framed photos of blues legends. The lighting stays low. The sound is raw and unpolished, which is exactly the point.
Drinks are simple and cheap. Beer, whisky, basic cocktails. Nobody comes here for the drinks list. The draw is the music and the room itself, a Bangkok institution that has been running the same way for over a decade on a street that keeps changing around it.
The Phra Nakhon neighborhood around it has a concentration of small bars and galleries worth exploring before or after. Soi Nana (the old town one, not the Sukhumvit one) is a ten-minute walk and has its own cluster of drinking spots.
