Before I became a somewhat resident at Jan Van Gent, I often came to the Hotsy Totsy Club, a bar on the other end of the Oude Houtlei and close to Labath, the nice coffee bar.
The Hotsy Totsy has already a long history (it already exists more than 30 years now!) and is mostly known as an artists or jazz café. The walls are filled with art and exhibitions by photographers and other creative masterminds.
The couches in the front are accompanied by some old lighting and in the back you can find games to play like Monopoly. If you like jazz, this is a must been address. On their website you will find their upcoming and past activities, and it mostly is for free!
