This Student Union is like no other. It is amazing and the setting is beyond beautiful. I recommend going in the summer when you can have your own table and you don't have to fight for chairs...
Babcock Dairy sells ice cream here, too. I posted photos of my son eating the Blue Moon Ice cream. Totally delicious no matter what flavor!
The cafeteria is pretty good, the prices are reasonable (although I am not a student on a student budget) and there are movie nights and live music as well. This is just the heart of the summer when it comes to living or visiting Madison, WI.
