Based on the giggling masses that spill out of Club Retro, this is clearly one of the most fun nights out in Poznan. You might need to get blazingly drunk to appreciate the retro karaoke that is a staple here – it makes it easier to laugh at that bad rendition of Bananarama’s “Cruel Summer” – but the beers from local brewer Fortuna makes that easy. And admission to this trip back in time is always free.
