One of the most popular of Krakow’s sushi restaurants, Zen attempts to be as authentic as possible, with a dining area upstairs where diners kneel on a tatami floor. In the intimate downstairs section (you get chairs here), dishes are categorized by color according to price, claret and gold being the most expensive. A green plate (20 z) features treats such as gilthead, eel, and sea bass nigiri, and maki of salmon, avocado, and Japanese mayonnaise. Sushi is extremely popular in Poland, so don't be nervous about trying it here. The quality will be high.
