For the money, this place is an great value. It has a nice old school charm and they make the best martinis! Martinis are $9.50 and beers were $5.00.
Unlike many higher end steak houses, Wonder Bar's steaks come with your choice of one of three salads (Warm Bacon Spinach salad, Wedge Salad with French Roquefort, or House Salad with house made oil and vinegar dressing) and a side. I had the Asparagus Hollandaise and my dinner partner had the double baked potato. The asparagus was a little small, but really, I'm there for the steak so I didn't mind.
I ordered the Cowboy Steak (rib eye) and my husband had the Wonder Bar Signature. I also added mushrooms. I love a place that gives you the option of "Blue Rare." The steaks did not disappoint. They were huge (seemed larger than even the portions described), cooked perfectly, and nicely flavored.
Because it's by the Alliant Convention complex it's busy. The tables are four tops but with all the food you get and drinks, four would seem a bit cramped.
Will definitely come back when we come through Madison again.
