Apparently St.Patricks day is a big thing in Slovenia? It's an interesting experience listening to a Slovene Irish folk band. Not sure id recommend it, but they were giving out free Irish coffees so no complaints! Ljubljana is a really nice place, the people are very relaxed and friendly. It doesn't have a lot of tourists either, which is a welcome change to the usual people walking around a city looking at it through there camera lens'. Made some great friends and had a lot of fun here.
P.S. Slovene beer is cheap and much better than I expected.
