I think whitewater university (the water park) might be closed, not sure though. Besides the stuff everyone else mentioned, theres also "Sleepy Hollow Sports Park" sort of over by the fairgrounds, nothing special really, but they have go-karts, batting cages, mini-golf, and a par 3 golf course. The new science center is suppose to be really cool, I haven't been down there yet though. I'll probably take my niece one of these weekends :P I'm not really a fan of big chain restaurants, heres a couple of my favorite restaurants around here... Tumea & Sons, old school italian place, and its right by the stadium Claxon's, bbq/rib place, its in Altoona (east suburb of DSM) or Kin Folks texas bbq (across the street from the claxons actually) if you're in a hurry Iowa Beef steakhouse is good too, although I havent' been there in awhile. Sam's Egg Roll on the south side, its a tiny place in an old strip mall but some of the best chinese around here. http://www.dmjuice.com/apps/pbcs.dll/section?category=juice Thats probably about the best site for finding random stuff to do on a specific date in des moines.
