This club is really close to the harbour of Antwerp. If you are looking for a nice place to enjoy techno and electronic music it is a rellay nice place. They have free techno parties on tuesdays called Dienstag which means tuesday in the local lenguage and also on thursdays called HMWRK. They are also opened during weekends but the price will be between 10 to 20 euros depending on the party but trust me, I have been in the free parties mostly but also in the most expensives nights and its totally worthy, people is really nice and chill, lights are cool, DJ's are also nice and close to the public and you have quite a big smoking area with sofas and tables if you feel like resting from dancing a bit.
So if you enjoy techno music, nice people and nice parties, Club Vaag is your place.
Here it's its facebook page so you can check events and pictures.
