We walked here from a nearby hotel on a Sunday night in low season. The place was packed and we waited a short time for a table.
The mains were better than average and the service was friendly.
I hadn't heard of brown omelettes (kaiserSchmarren)before so I tried it out. This version of a Austrian pancake was amazing. A must try. And having now tried a few other restaurants for the same dish, this place is easily the best.
