This restaurant is located in a residential area about 200m from the Pilgramstrasse metro station. We arrived mid-evening, mid-week to find the place already full and buzzing. However, the staff were very welcoming and gave our group the last unreserved table. My own meal - the house special, a diced beef stew - was excellent and the beer (zwickl) was good; the special requests of my fellow diners were filled without fuss. Our server spoke excellent English. The bill was significantly lower than similar premises in the central area.
Overall, we felt very at home and I will gladly return - although I will attempt to make a reservation! Well worth adventuring outside the Innerstadt.
