Rainbow 4
Rainbow 4 occupies the left corner of Nana Plaza's second level and runs one of the largest lady rosters in the complex, with 70 or more dancers on busy nights between 22:00 and 01:00. The bar has a direct, no-nonsense reputation: expect bar fine questions within your first couple of drinks. If you want efficient, low-fuss arrangements, that directness works in your favour. The quality is consistently above average for Nana, and management keeps the lineup fresh.
What to Expect
A large, busy go-go bar with an assertive but not hostile atmosphere. Staff are professional. Ladies tend to open the bar fine conversation early, which is either efficient or off-putting depending on what you want.
Fast-paced and transactional. Good lady quality and solid selection, but not the place for a slow, relaxed evening.

Insider Tip
Come after 22:00 for the biggest selection. If you are here to people-watch rather than bar fine, set that expectation early or staff will naturally assume otherwise. The bar gets very crowded on weekends.
Full Review
Rainbow 4 fills a corner spot on Nana Plaza's second level with a large rotating roster of dancers, typically 70 or more on busy nights between 10 PM and 1 AM. The space is functional: a central stage with surrounding seating, standard bar lighting, and a sound system playing commercial EDM and Thai pop. The layout prioritizes sightlines and efficiency over atmosphere.
The service style is direct. Expect bar fine conversations early in your visit. Staff and dancers operate with a transactional efficiency that experienced visitors appreciate and newcomers sometimes find startling. The quality of the lineup is consistently above average for Nana, and management keeps the rotation fresh. This is a venue that knows its purpose and executes without pretense.
Rainbow 4 is the high-volume option in Nana Plaza. Angelwitch beats it on entertainment, Spanky's beats it on warmth, and Billboard beats it on spectacle. But for sheer selection, especially later in the evening, Rainbow 4 fields the deepest roster. It's the venue for visitors who know exactly what they want.
Come after 10 PM for the full lineup. If you're visiting for the atmosphere rather than arrangements, set that expectation clearly and early. The bar gets crowded on weekend nights, so solo visitors may find weekdays more comfortable.
