My father and I have just visited krakow and went to pieciolinia smakow as it had been recommended to us by some friends who had visited recently. Their recommendation was spot on. The gentleman who served us was attentive, spoke good English and very welcoming. We both had the sirloin steak, cooked to perfection and the best steak either of us have had in years! We only had the 2 steaks and a bottle of wine but the price came to about £34 in total.
Definitely recommended you won't be disappointed!
