I've already been here twice and it's just opened recently. And I'm still amazed by the clever design of every little detail. The concept is to offer what's closest to organic burger, and all the ingredients, carefully selected, come from Croatia, preferably from family farms. The burger itself is not a perfect 10, but the quality is very good and a lot of effort was put into it. The menu is by far the most creative among Zagreb's burger bars, so you can have a burger with egg, truffles, pesto, radicchio and toasted hazelnuts... Excellent homemade sauces really give it that extra kick. Drinks selection is absolutely fantastic for such a small and specialized joint. Artisan Croatian beers (draft San Servolo!) and very decent wines by the glass is something you rarely see in much bigger establishments. Staff is very friendly and dedicated, and last but not least - they even thought of kid-friendly features.
