Before you visit this place you should keep in mind that this area has rather cold climate and people acustomed to physical labour. Why this is important? To understand the food served.
While they do offer pizzas and similar popular things (ie calamari, french fries and etc), you should really go for river fish (trout) or local meat specialties - licki rucak, sarma, gulas. These will not dissapoint you, but they are not light meals. :) Servings are large. Also, the beef soup, home made, very good.
I will visit again. :)
