The new Southbank just reopened on August 5th, 2016. It moved from Jalan Aceh to Jalan Sumatra, a street with several other nightlife venues. It is central and trendy location that I recommend if you are not familiar yet with Bandung. You can stay nearby in the Crowne Plaza Hotel, one of the best in the city.
Southbank intends to keep the same concept as before. It is a bar/lounge that turns into a nightclub on weekends and for special events. More classy than its competitors (Sobbers, Mox, Shelter), it is popular with an upmarket crowd that includes a lot of Indonesian-Chinese.
The venue is kind of similar to Empirica or Potato Head Garage in Jakarta. It is a high-ceiling warehouse with basic design except for a few artsy/vintage details. They will have regular DJ events that you can check on their Instagram page below.
The dress code is implemented so you should wear trousers, shirts and shoes. Locals dress up in Southbank as you can see (pics from the opening night):
