Great place to buy wine! The staff will help you out if you need to find something specific. They also have a section dedicated to Wisconsin wines. Some of the Wisconsin wines can be found elsewhere for cheaper, but the selection at Steve's alone is worth a visit. My friend found her favorite wine from Spain here. They not only have a good quantity of wines, but the quality is great too.
They also sell cheese and candy. I would suggest picking up some of Christine's salted caramel. So good and local too! Oh, and they have beer, but not a great selection.
