We tried ice cream at the Iowa State University Creamery today and it was excellent! It was my first time on campus and I was surprised at how easy parking was. I attended the University of Wisconsin and parking is a nightmare year-round there.
The East Parking Deck is closest to the Food Sciences building and the Creamery is on the 2nd floor. Once you enter the building, you'll see signs directing you upstairs toward the ice cream. There are a few tables available inside, some benches in the hallway and a courtyard area to eat outside as well.
