"German" restaurants in the USA are something I know only from documentary films about Disneyworld and ... the TV comedy show "Chuck".
I know no professional German cook who is really into that kind of cookery. There are indeed very German
restaurants in Germany too
They call themselves "gutbürgerlich", but they are dying out and the remaining restaurants of that kind are usually during the week only pubs
. They are visited on Sundays by families who want to give mother a free day and that's often the only à la carte
business they have left. In main they make profit by renting out halls for wedding parties, birthdays and anniversaries... on thus occasions they also provide food but usually there is then "an experienced housewife" in the kitchen.
The German cooks I know sometimes promote traditional German dishes, that's right. However, if they do so, they always refine the dishes in a way that only the ingredients are "original". (Their main goal is usually to promote local product!)
Well, there are traditional German dishes I love too. Like "Dicke Bohnen"
That's why I always get hungry when I see Italian Western starring Terence Hill and/or Bud Spencer. (The latter once starred in a very successful flick titled "Even Angels eat Beans" :lol) "Dicke Bohnen" also remind me on a certain ancient episode of "Rawhide" (I sometimes watch TV in the middle of the night because my stomach hurts from being to full of "Dicke Bohnen") where the cook tells a cowboy: "My food is hot and makes you full! Therefore, what I do to it, is nobody's business!"
Yeah, well, maybe the problem is that there aren't enough cowboys left in your country...
