Disappointing.  Perhaps it was due to high expectations, but my wife and I left less than satisfied.  When we decided to move out to Denver, my aunt told me only one thing, that I had to eat at Westfalen Hof.  She told me it was one of the  best and most authentic  german restaurant she had ever tried since moving to the United States from Frankfurt.  I have had more than my fair share of German food, in both Germany and the US.  I am familiar with waiting for the good stuff, so as our wait crossed the 60 min mark (with only 3 other tables occupied) I had high hopes.  They were not met.  The  Jäger schnitzel was alright, but the Rot kohl and sauerkraut had much to be  desired, as well as the service, which was...well, it only seemed to be available in passing. Although, to be fair, if you are a regular, you will receive exceptional service and constant attention.
If I were to be, say, driving down that particular road and hungry, I may be inclined to give them another shot. Â But I don't plan on driving that far off the beaten path any time soon.
