Cwaniak Warszawski

Cwaniak Warszawski, literally "Varsovian Trickster", is a retro-style restaurant combining classic Warsaw folklore and a classy communist-era feel. The city's culture, art, tradition, and classic dishes are all on display, complemented by Varsovian music. The unique style and interior design make Cwaniak Warszawski an original experience in the city, while the menu combines the best of local tastes and Polish favourites such as dumplings, roast duck, pork knuckle, and soups.
