During my short week trip to Tokyo to visit my friends, I visited a jazz-themed cafe in Shibuya. A little difficult to find the place for newcomers in Japan, Google Maps will do the trick. (I am not familiar with Tokyo at all!) Once you reach LAWSON, be careful not to walk further, you should see a restaurant/bar on the ground floor and right beside it is an entrance to the building. Enter the small entrance and make your way up the stairs surrounded by brick to the 4th floor.
