Yes, it may look like a typical WI supper club on the inside, with the vinyl covered seats and tables, and slightly hokey country decorations (fake ivy and pastels with farm implements on the walls). But Heiney's has the best steaks in the Midwest--did you hear that Chicago?
Prices are comparable to a Chicago steak house, but I suspect there is less inflation, due to the quality of the meat. Last time I went in, I ordered "Steak Muscoda": fillet mignon topped with blue cheese and morel mushrooms. It was superb.
The meals are served with salad, bread and choice of potato. I recommend the spinach salad with the homemade raspberry vinaigrette. Chicken and fish are also on the menu, for the non-beef eaters. I also recommend ordering the crawfish appetizer--spicy and delicious.
A full bar is also inside: wine, beer, and mixed and blender drinks.
Expect to spend about $30-35 per person.
