Time Out says
Not only is Capuciner convenient, facing the Cathedral, and filled with locals, but it's fairly priced, most dishes in the with most dishes in the 40kn range. They specialise in big salads; excellent house pizzas with toppings like prosciutto, spinach and artichoke; and pastas, gnocchi and numerous veal dishes. This is a very good spot to grab a solid meal during a long day of sightseeing. From Kaptol, walk through the bistro to the back dining room with wooden-beamed ceilings or head out to the winter garden/summer terrace, which you can access through a back door from the building's side alley.
