This is a very good wine bar located in the centre of Ljubljana at a pleasantly distance from the most hectic tourist crowd. They have an impressive wine list, and they serve most of their wines by the glass. We visited there a couple of times and the different waiters had a very good knowledge of their wines and Slovenian wines in particular. We were treated to taste some special Slovenian orange (the colour, not the fruit) wine free of charge. We did not have any meals there, only some tapas which came with the wine.
You may want to find a table outside.
