Buffets are known for being cheap, but not necessarily good. This one is both, a consistent staple for budget-conscious Poles looking for comforting classics. You’ll be tempted to fill up on deeply mushroomy soup, crispy fried chicken, meat-filled piergoi, thick goulash and poppy-seed cake, but save room for the potato pancakes, among the city’s best. What’s the trick? The constant stream of staff carrying them fresh from the fryer to the buffet line, and the constant stream of diners wolfing them down to ensure high turnover.
