Restaurant UNO & U-ONE Bar


Pleasures for every palate

Seasonal salads, Viennese-style schnitzel with potato salad, or delicious desserts? Whether you want to unwind and end your day on a cozy note or enjoy a midday snack, we have the perfect place for you! Our chef and his team are also big fans of vegetarian and vegan cuisine. A new breeze is blowing through the culinary landscape here, always fresh because homemade tastes best. We cook for vegans and flexitarians as well as die-hard carnivores – seasonal, with a pro-veg focus, fresh and locally sourced. On the menu you can expect to find classic Viennese dishes, beef specialties and purely vegetarian delicacies. Whatever you choose, our terrace offers you an unsurpassable holiday atmosphere: outdoor dining in the middle of the city.
