One of the best options on the Old Town Square (generally not the place to dine if you want to retain your street cred), Pod Niebieniem serves Polish food with a contemporary twist and actually caters to vegans - score. Certified by the Wielkopolska Culinary Heritage Network and awarded at various food festivals, they pride themselves on their beef tartare, Zielenica trout, and sour rye soup. A nice wine list rounds out the offer.
