​Brainwave for the heatwave from the alternative guys responsible for the Plac Zbawiciela mayhem of Plan B. Barka is basically a flat-topped barge, pimped up to look modern and cool by the designers at Project Praga. Once you’ve navigated the narrow gangways and the security blokes you’ll find a bar, concert and dance area. A whole series of gigs and guest DJs appear throughout the summer and the venue is regularly mobbed with partygoers. In fact it gets so busy that many visitors prefer to just make use of the riverbank area in front of the moored barge to chat and listen to the music coming from onboard. Our sympathies go out to you if you need to make use of the portaloos (Toi-toi in Polish).
