Rainbow 1

Rainbow 1 sits on the ground floor of Nana Plaza, where Soi 4 spills off Sukhumvit under that towering red NANA sign and the palm-framed neon that still bills the complex as the world's largest adult playground. First floor means you feel the strip before you even order — taxis idling outside, the plaza glowing overhead, tourist and expat traffic drifting in after dark. Inside, the room leans purple and pink: a disco ball turning over mirrored walls, poles on the stage, dancers in fringe and sequins working the floor while tables face the show. The looks run glamorous — pink tassels, blue sparkle, gold chains — classic Nana go-go heat, incall once you've stepped off the sidewalk and into the booths.
