If you have ever eaten at an exceptional German restaurant, you will be ruined for life. Years ago, the Haus would have gotten 4 stars. But after being turned on to a little gem in Gibson City, IL called "The Bayrn Stube" my appreciation of fatty meat and spices stuffed in an intestine laid on a bed of sauerkraut and red cabbage has been forever changed. Haus just doesn't quite measure up. The cup of soup before the entree tasted like it came out of a can and the bread looked like the sheets of Hawaiian bread you buy at wally world. Probably the biggest turn off was when they brought out the brown mustard still in a plastic squeeze container. 
My meal was the Nuernberger/Kassler combo for one, and I had enough left over for breakfast the next day. Their sausages seem to be of lesser quality than I would get at Sunflower and the red cabbage had some pork gristle in it. Not that I mind a little pork fat in my cabbage, but not chunks, and definitely not gristle. My friend ordered the Huehner (Chicken) Schnitzel, which had a very good flavor, it was the best part of either of our meals. They do have a nice selection of good beers on tap, no Aventinus though. 
If the food was anything other than German, it would get 2 stars. It is nice to have somewhere to get a schnitzel when I'm in the area, but I wouldn't drive out of my way to eat here.
