Häppies is built around one dish: the yeast dumpling, called a Häppie.

Six varieties are on the menu, each with its own name. "Bärbel" comes with goat cheese filling and cashew-arugula pesto, "Maria" goes Mexican with soy mince. The classic stays true with plum jam, poppy seeds, and brown butter. The kitchen cooks fully vegan. The café sits on Dunckerstraße in Prenzlauer Berg — small space, one concept.
