I have a feeling that we just scratched the surface of the very small restaurants and coffeeshops in Livno, Bosnia when we were there to visit our daughter, son-in-law and grandson. I'd highly recommend a dish called "burek" which was described to me as a Bosnian fast food.
It's made from thinly-rolled dough with various stuffings and fashioned into a snake-like shape and then fried. It's served with a liquid kind of yogurt. It was great. It was more fun eating with our almost two-year-old grandson who has an enthusiasm for eating.
We ate this dish at this very small eatery and ate it at another time when we got together with our daughter's neighbors. I'd rate it as a "must try" when you are in the area.
