Unfortunately, the restaurant was not convincing across the board.
Starting with the fact that there was no orange lemonade on the menu, the sauce for the roulades was very salty, the (unusually greasy!) Schäufele was still ice cold inside, the potato salad was quite frosty (we would have found it more pleasant at room temperature), the schnitzel was very dry, but the fries were fine... however, when we got home we discovered that we had even been charged for a drink that we hadn't even consumed.
They advertise that they pay attention to gluten-free cuisine, but one eater with celiac disease didn't feel well after eating... but it can't be said with certainty whether it was caused by gluten.
Overall, only recommended to a limited extent.
