Concierge.com's insider take:
Though synonymous with seedy red-light activities, Patpong in recent years has attracted a small number of upscale, comparatively wholesome establishments. While they don't entirely offset the thriving sex industry that spills into the pedestrian-filled side streets off Silom Road, each is an unexpected haven worth seeking out. Well-dressed Thais, most of whom seem to know each other, toast and talk inside the low-lit chill-out rooms stacked atop one another at Tapas Room.
Jazz (both Western and Thai-style) is the draw for most visitors, while others snag a comfy cane seat outside for prime people-watching (open Thursday through Saturday from midnight to the 2 am curfew). Around the corner, Funky Dojo
manages to stay open until 3 am, offering a street-front scene that's entirely sleaze-free, instead attracting international DJs and a sophisticated mix of international and Thai clientele.
