I'd say the tornado was the essence of Wisconsin supper club but really most Wisconsin supper clubs are overpriced and bland in my experience only surviving by being the best place in the county to have a wedding reception or a fish fry.
Tornado has the same look and feel but their meat is generally much more flavorful and well prepared than the standard. The huge bone-in rib eye is delicious, juicy and full of flavor. The cocktails are strong and they make some of the more obscure classics well.
Generally had good service, even when ordering pretty damn drunk at 10:00.
