Wedding Reception Ideas?

Anyone know of any decent, laid back and affordable wedding reception venues in the Des Moines area?

My fiance and I are getting married over seas, and are hoping to have a light fun, and affordable cocktail party when we return home.

We've contacted numerous hotels but all of their packages seem to be for an all out reception with lots of food, hors dourves, table settings and all that jazz. We just want a bar, dance floor and casual environment.

I'm fresh out of ideas. Thanks for the help.
