Smart modern looking airport but poor facilities for shopping eating and drinking. What's more many of the shops were closed - and this in the middle of the day. My advice is not to go to departures too early and certainly do not go to the gate (and security) until the last minute or you will be stuck in a drab room with little seating and no facilities at all. You need to get rid of Serbian currency before leaving the country because you can't get it exchanged outside Serbia but there are no exchange facilities at the airport! Presumably this is to ensure that people spend any excess money at the airport.
