There’s a minimalistic kind of elegance to this intimate restaurant inside the Sava Boutique Hotel on the banks of the Vistula river – think whitewashed walls, dimmed lights and neatly dressed tables. High-quality ingredients are at the bedrock of the cooking, which shine brightest in uncluttered, subtle dishes such as mackerel with horseradish, dill and caviar. While there is an à la carte, go for one of the two tasting menus for the full experience.
