Let’s start at the beginning. First, there actually is an animal in Slovenia called the Human Fish. It’s not actually a fish nor is it human, it’s an amphibian, and is the namesake for a brewery that led the craft beer revolution in Ljubljana.
You can visit HumanFish at their brewery in Vrhnika where they have a cosy tap room, but since they are faaaar from Ljubljana (as we locals say when something is 20 kilometers away), another option is to find it on tap in the city. Luckily, there are many spots that carry their beer, including Cielito Lindo, Daktari, Petkovšek, Premier Pub, Gas Station, Irish Pub, Alter, and Niša at Dobra Vaga Gallery to name a few.
