A short walk from Oliwa Cathedral lies the veritable pierogi paradise Mandu. Pierogi are a sacred part of Polish cuisine—a simple dish that everyone remembers from childhood, usually with a hint of nostalgia—and Mandu respects that tradition while also devising new, creative variations. In addition to classics like minced beef with onion and bacon, Mandu serves international versions such as spicy, deep-fried Korean dumplings with pork, tofu, kimchi, ginger, and leeks. Everything here is made fresh to order, meaning you might have to wait during busy times. Instead of getting impatient, use the few extra minutes to watch the skilled cooks work in the open kitchen.
