There are a few German restaraunts here in the area,but we have never tried them.We did eat at Oma's Haus in New braunfels.It was alright,but my dad was not impressed.A german family from the old country has taken over the old Krause's Cafe in town so I may try it some time.
Mader's in Milwaukee must have changed from years ago.I know my dad ate there once or twice in the past.
My cousin Hildegard he said used to make cheesecakes using an old family recipe and sell them to Mader's who later bought the recipe.My dad felt grandma's cooking was best.She used to make all the german dishes .Her family the Steldts were Prussians from Riga, and grandpa's family from Bavaria,so my dad grew up with a mix of both styles of cooking.
And different parts of Germany just like,in France,China,etc. do have regional differences.
There is an Alsatian restaraunt in Castroville,west of San Antonio,though I have never eaten there.
The town was named for Henry,Count Castro who brought Alsatian settlers to Texas.
There are lots of germans here,but they are kind of scattered and just not the old ethnic neighborhoods like in the old days,plus they assimilated in to American Society pretty well.
There was a Polish and a Hungarian restarunts here in town,but I don't know if they are in business anymore.
