If you're thinking of boarding one of the several dining vessels along the Wisła River, make it Barka. This Dutch cargo barge dates back to 1889 and was once significant enough to the history of water transport to be featured on a Dutch postage stamp. Since then it has been modernised by Polish craftsmen with thrilling results. Enjoy an afternoon cocktail in the sun above decks, or descend into the spacious hold refitted with wooden floors, a sculpted bar, fireplace and skylights that let in plenty of natural light. The drink lists are duly impressive, and the menu of creative designer food is thoroughly enjoyable. Recently Barka has become host to some of the best, most earnest electronic DJ nights in town, so cast an eye to their FB page. Utterly stylish and surprising, climb aboard and become a hipster socialite.
