This is a very popular restaurant in a popular, touristy area of Munich - therefore it gets very busy!! It is best to arrive as early as you can if you want to get a seat, in the evenings we saw it was packed and had to wait until lunchtime on our last day in Munich to try it.
We ordered the six sausages with sauerkraut, and tea and coffee to drink. We sat outside and it was already very busy when we arrived. The service was quick and efficient, and pleasant. We could smell the sausages cooking over the fire and this added to the atmosphere.
The portion was reasonably sized, and reasonably priced. It was the first time I'd eaten sauerkraut, and it is definitely a good accompaniment to those sausages.
As this place gets very busy, you don't feel like lingering over your drinks, but the staff didn't rush us.
I would happily eat here again if I were in Munich.
