Well burek and pita are different because bureks are made with leafy pastry.. I don't know how to explain (try going on wikipedia or some serbian cousine web page)... Bureks can be made of meat, cheese, mushrooms or some herbs :) and this is for "pita" :) http://en.wikipedia.org/wiki/Pita

Well, I had an experience of Serbian food and its really amazing! Pljeskavica, burek and other stuff named here are nothing comparing to "sarma", "pasulj"(beans made on Serbian way), "proja" and "kajmak"... there are many others but these are really the best... I would love that somebody opens a fine Serbian restaurant in NYC :)

Try to find these foods on the internet or maybe on wikipedia :)
