This is the Cafe Van Leeuwen, a cosy jazz place in the center of Amsterdam where you can also have a nice lunch or dinner.
But probably the best thing of this bar is its terrace in the second floor... You can have your drink while sitting at the windows!
Every Sunday there is a jazz concert from 5pm. You can check the agenda at their website
Cafe Van Leeuwen is located in Keizersgracht, in the corner with Utrechtsestraat
