I last flew through Ljubljana airport at least 5 years ago - maybe longer. It's been improved considerably since then. Most of these improvements are very nice - lots of steel, glass, nice chairs, a decent duty-free (where I got a bottle of viljamovka). The less-good improvement is the weird bus ride of 10m that you have to take after disembarking from the plane to get you to passport control.
I was amused by the glass "specimen cases" they have for smokers:
If you ever needed motivation to give up - I would have thought that being stared at by everyone else in the departures lounge would be pretty effective :-)
