Don't go hungry. If you do you might actually die waiting to get in and get food. You need to get here about an hour or so before your stomach starts grumbling so your appetite can build and you don't end up eating your menu.
We arrived around 6:30, two adults and one 13 month old. Requests for table with highchair was left with the host. 30 minutes pass and we are seated at a booth, no high chair allowed. Rather than wait for a table to open we take the booth and decide wrestling the baby will help burn calories from this calorie laden German feast we are about to chow down on. We order our schnitzel and sausage and it takes about 45 minutes for the food to come. So we fill up on 3 slices of rye bread and drain our drinks waiting. Food arrives, hot schnitzel topped with cold sauce. Cold spatzel topped with coagulated sauce. Semi warm potato. We are starving and service was slow so I start inhaling my food. I think it would have been great had everything on the plate been the same temperature.
They definitely need more servers, getting a refill was next to impossible. The whole process was slow. We skipped dessert simply because we didn't have another 45 minutes to spare.
