Nana Plaza is one of the other red light districts of Bangkok. The best way to describe it is a dilapidated carnival from hell. It's a depressing place with gogo bars on strewn about on three floors of the plaza. The main problem with Nana is they dont have any regular nightclubs if you are looking to have a "normal" night out. Nana Plaza hotel across the street has a nightclub in its basement, but its old and rundown, there are far better options in Bangkok. Outside of Nana Plaza there are a fair amount of sports bars, which are a much better place to grab a drink.
