As a tourist, I entered Greco on the Market Square. I am lacto and gluten free. I am also allergic to glutamine. I informed the waitress named Kasia about this and asked for advice on what I could eat. She literally snapped: I can eat what's on the menu, but at my own risk. Never again at this restaurant. The waitress acted as if she was doing me a favor, she was grumpy and unpleasant. Additionally, I paid with a PLN 200 banknote. He spends the rest PLN 75. in coins of PLN 1, PLN 2 and PLN 5 and one banknote of PLN 10. Because of the rude service I DO NOT RECOMMEND
