U Bukanyra is the little house boat down by Stefanikuv Most. This bar's various house DJ's turns this place into an big electronic music party every Thursday thru Saturday. The boat has two decks with different opening times, the top deck is open and cooler while the first deck can get pretty hot during the summers (see opening hours below). They serve Holba beer on tap and a variety of spirits at an average price. U Bukanyra is one of the better bars in Prague when you want to listen/dance to good electronic music, and since it's right on the river with outdoor tables on deck two, it's even better in the summers. They also have foosball tables on both decks.
