Yes, I drove from Zagreb to Dubrovnik. I was very pleased when restaurants served Italian food. I was not aware there were dozens of ways to prepare squid in Croatia and Bosnia. But, squid for breakfast was one step too far. So a pizza was a major treat. I liked everything else about the former Yugoslavia, especially having a rental car (also in Slovenia).
I almost got in trouble in Sarajevo because there were so many very attractive young Muslim
men, "seemingly" waiting to be picked up. They were actually waiting for a straight nightclub to open.
