This establishment run by Markus Mraz and his sons Lukas and Manuel is a real institution on Vienna's gourmet scene. They serve a surprise set menu comprising a whole series of small courses. They like to concentrate on one main ingredient, which forms the basis of the menu. This approach results in dishes such as their Korean-style chanterelle goulash: a true taste explosion of roasted notes, mild spiciness and full-bodied mushroom flavour. The place has a chic, modern feel and the atmosphere is totally relaxed – they don't stand on ceremony or formality here. In one of the three rooms there is a clear view of the open kitchen. Charming service comes courtesy of attentive and very well-trained staff, not least the sommelier, who maintains a terrific wine cellar and guarantees perfectly balanced wine pairings teeming with interesting ideas.
