I have been before to the popular pierogi restaurant in Warsaw called Zapiecek. I was not very impressed with the food there, but I thought I would give a second chance to pierogies. So we took part in a cooking class in Warsaw to make our own pierogi. To my own shock they tasted better than the ones I tried in the restaurant, even though I made them with my own bare hands. I must be a very gifted cook (I'm not, I can barely make fried eggs), or the class leader is very good at this. We were very luck because the group that got together was a bunch of very nice people. The atmosphere was great and we really enjoyed it the whole time it lasted. It was about 4 hours+ in total, but seemed too quick. Absolutely recommended.
