Be grateful if you find an empty seat on a sunny day within 5 minutes of waiting. Cacao is one of the best ice-cream parlours in Ljubljana for a reason. While I can’t say much about the coffee, except it’s freakin’ expensive for the city’s standards, the sweet stuff is amazing. The prices are in general above average, but if you are a quality-over-quantity kind of human, you have found the right spot. Almost every summer they mix in new flavours and play with the existing ones. The staff is fast and nice (it always depends on who you run into, though) and always willing to explain the ingredients of a menu option.
If you catch the right time of day, you get the privilege of observing the slow setting of the sun over the riverbank skyline, absorbing the changing colours of the sky’s reflection on the Ljubljanica river.
The joint is a 30 seconds’ walk from the Prešeren statue, so you have no excuse not to visit them both.
