This IS as good as it gets for authentic German food in Arizona.
I went here with a large party for my birthday dinner. We called ahead and they were very accommodating. We enjoyed a variety of absolutely delicious cold beers to start it off in large 1 liter glasses. Schnitzel was crunchy and delicious, and I sampled the jaegerschnitzel as well that my wife had. Also phenominal.
For my birthday was was serenaded by an accordian player in German. I don't speak any German, so he may have been saying anything, but it was unique and very fun. Split tabs was not a problem and the staff was on top of serving us.
I can't wait to go back! Easy to run up a big bill though with all the delicious food and beer, but it was worth the money.
