I've just "discovered" this forum, and this topic. The opening post "Where have all the German restaurants gone?", is a question I've wondered about over the past couple of decades.
I've been to some of the better known German restaurants in the U.S., including Maders and Karl Rausch's in Milwaukee. I've been to Frankenmuth, MI, and concur that just from my brief experiences, it is more tourist than the home of top notch German cuisine.
Sadly, the same can be said for the created Bavarian town of Leavenworth, WA, where the best place, in my opinion, is King Ludwig's. It is decent but not up to the standards of Maders or Karl Rausch's.
An earlier post from a San Diego poster caught my eye:

Any one of you know a good German restaurant on the left coast? The Only one that I know of is in cold,expensive San Diego!

Having lived on the West Coast (CA, OR and WA) now for three decades (originally from PA), I oftened pondered the same problem. In my years of searching, I can recommend two.
Schroeder's Cafe in San Francisco (advertised as the oldest German restaurant in CA), and, in my opinion, the best: Horst Mager's Rhinelander in Portland., OR.
There are a few places in Seattle than are mentioned as worthwhile by others, but in my view, they don't measure up to the experience (quality, portion size, selection and ambience) of the two previously mentioned places.
Same with Southern California. From living in Orange County during two different periods, the search for a high quality German restaurant experience - after which you are already planning to go back - just wasn't to be found.
The Rhinelander in Portland is the best on the "Left Coast" to my way of judging restaurants.
