A lovely little restaurant in the old town, on the main touristy street of Grisia. We visited it 3 times in 2 weeks.
The decor and atmosphere inside are definitely Bohemian. The menu is slightly different from the "standard Istrian" fare found in most other places (eg, they have chicken dishes, which we hadn't seen elsewhere). My husband really enjoyed pork medallions served with prunes. I appreciated both the chicken saltimbocca and the chicken salad with dijon dressing. A word of caution: many of the dishes include sesame seeds, to which some people are allergic - best to check. Indeed, for the seriously allergic, probably best to avoid this restaurant, as everything presumably has traces.
A marvellous chocolate cake for dessert (they were out of the cheesecake each time, more's the pity!).
Some interesting local wines and the "main man" is very knowledgeable about them and helful in making a choice if you're not sure.
