This restaurant is a reasonable way out of 'town', being about 2 miles away from Checkpoint Charlie. It is well, well worth the trip.
I visited with my wife and two children, 9 & 5, and we did not have a reservation but it was only a Thursday night. We just about got a table and there was no spaces after us!
The menu is as simple as can be, half chicken or two types of sausage. The sides are equally limited, a potato salad or Sauerkraut. The wine list is good, the beer list is good and the service is fantastic!
The whole feel of the place is authentic and the food absolutely delivers.
It is excellent value for money and one of those places that you are genuinely glad you visited.
