Considering the simple concept, and the fact that it's discreetly tucked off a corridor full of noisy music clubs, this is a surprisingly sophisticated restaurant, featuring a beautiful timber ceiling and modern art on the walls. While some familiar Polish standards share the menu, train your attention to the first page for an introduction to Polish 'kasza' - that is, groats or hot cereal. Choose from pearl groats with chicken curry and black olives, or millet with pumpkin, turkey and garlic sauce. A tasty, filling meal on the market square for under 30zł? We approve.
