Rainbow 5 is a well-known Agogo bar in Bangkok's Nana Plaza, located on the second floor and easily accessible via the right-side elevator. This bar is one of the Rainbow series, considered one of the larger establishments in Nana Plaza, adjacent to Rainbow 4.

Rainbow 5 operates every night from 19:00 to 02:00, offering extended entertainment options ideal for nightlife enthusiasts. Drink prices start at approximately ฿150, Barfine around ฿1,000 - ฿2,000, and Lady Drinks about ฿250.

Rainbow 5 is renowned for its large space and multiple stages, accommodating up to 60 girls each night, creating a lively atmosphere reminiscent of a nightclub. The stage design includes a long bar counter and stages on both sides, each capable of holding up to 30 girls, with central seating ideal for viewing the performances.

The girls at Rainbow 5, like those in other Agogo bars, typically wear bikinis or lingerie with high heels, with occasional semi-nude performances, though not every day. Compared to Spanky's and Angelwitch, the shows here have fewer variations and a milder scale. However, the main selling point of the Rainbow series is the young girls with appearances that align with Asian aesthetics, so those who prioritize looks can give it a try.
