Time Out says
Municipium is set in a grand Habsburg-era building, tucked away in a quiet courtyard right in the centre of town. Door staff greet you at the entrance – decorum is all. The menu is vast and fish-oriented, most of it priced in the 300kn/kg range, which is very reasonable considering the quality of service, presentation and the fare itself. Courgettes, wild asparagus and other greens get a look-in and the wine list runs to 150 (mainly Croatian) varieties.
