Sounds like somone hasn't spent much time in DSM that isn't work related. Here are some things many people think are great, most of which I do not believe are available Iowa City:
1. Wells Fargo Arena and all of the concerts/acts/events that come through.
2. The Civic Center and all of the shows that come through. I get IC has Hancher but that is mostly art student crap that no one actually wants to see. In contrast, we have seen Hamilton, Dear Evan Hansen, Wicked, the Lion King, and a few other shows in the past few years.
3. The Iowa Science Center
4. Blank Park Zoo
5. The downtown farmer's market which is like a huge game-day type experience every weekend, with live bands playing on multiple street corners.
6. Various "fests" that are held downtown throughout the summer (Art Fest, Oktoberfest, 80/35 music festival, etc). The farmer's market and fests and such can be seen here:

7. A vast system of bike trails and bars/places to stop on them
8. Principal park and the I-Cubs
9. Relatedly, the Iowa Wild and the Iowa Wolves
10. The Principal Charity Classic (golf)
11. A pretty good bar/dining scene that doesn't cater to poor students (for the most part)
12. The nitefall on the river summer summer concert series
