Unfortunately, restaurants and bars still have "smoking or non" in Serbia, and in practice it's just smoking everywhere. So if you're hit with nostalgia and wish to smell like ashtray after going out - come to Serbia!

There is one small negative of banishing smoking in the rest of the world is dissapearance of ashtrays from modern cars. You don't have to smoke but it's convenient to have some kind of small trashcan for other purposes. Yes, you can buy third party one for a cupholder, but it's typically cheap and not nearly the OEM quality.
