Balsam is a relaxed place to be on a Friday or Saturday evening and night. They don’t have any posh guests (most of the time). You will definitely meet some people who just came out of their beds, and some night owls.
Balsam hosts good concerts (this will mostly be some little known but very pleasant bands or DJs with chill-out music. But I have also heard some hip-hop music here).
They have a lot of space at the front. I just love standing outside, with a glass in my hand, watching people talk and listen to the nice music played inside.
