This would be a close and fun place to visit for those who love indoor nature gardens.
Very Child friendly place to visit, also fun for adults. They sometimes have limited time exhibits, worth checking into, if you have the time.
Very good pizza, I will always recommend the Crab Rangoon pizza.
The wedding venue is also a brewery/restaurant with good food and a good selection of beers.
If you wanted to check out Iowa's art museum, I would recommend it. I think all of the art is very pretty, and the atmosphere is nice.
Another family friendly attraction close to the downtown area.
