If you go to just one jazz bar in town, this should be it. Right on the market square, this basement club is rightly one of Krakow’s most popular music venues. All the big names in Polish jazz have played here. The regular appearance of foreign guests and a flexible music policy—blues, R&B, and folk—mean that Harris fills in summer and winter. It’s opening until 2am and serves a selection of 20 cocktails from a long, busy bar counter to keep the party going.
