Kansas City native, and I can tell you not a whole lot going on here.
That said, here are a few attractions that I think are worth visiting in the KC area:
-Country Club Plaza (There are fountains and a small park that run adjacent to it)
-Nelson Atkins Museum
-Definitely check out the steamboat as they are moving it out of Kansas City in a few years
-Downtown for the power and light district (bunch of degenerates ruin the scene past 10pm, but it's fun before then), also the streetcar that runs up and down Main street
I'm not sure what type of food you're into, but if you're up for BBQ, I highly implore you to hit up Joe's Kansas City. You will enjoy it. There are three locations. The 47th Street location, I believe, is the original Joe's and has an old school gas station attached. The whole place has a cool nostalgia to it.
