One of Warsaw's favourite venues of recent times has returned, with the mermaid's song (from where the name hails) carrying across the river to its new location in Praga Koneser Center. The postindustrial style fits in with the revamped ethos of Syreni Śpiew; a place to take in the atmoshphere, and create memories. With 4 floors, 4 bars and 3 stages, this is the perfect spot to sip away and eat during the day, and party the weekend away. Slide inside and let them ply you with upscale cocktails and top shelf whiskies while you schmooze to some smooth tunes. While it's a low key high class chill during the week, there are plenty of events to enjoy before the weekend vibe goes sublime with carefully curated live music and DJs that keep the parties going all night long. Check their Facebook page for all the latest events.
