I am not sure what is in this building because I never when inside, but the outside is completely made of corn! It is all different colors too. It kind of looks like a palace too. I have seen it on TV before and it is kind of cool to see a place on TV that you have been too before. I really liked it because it was out in the middle of nowhere, and if you have to drive through South Dakota, it is a fun stop along the way, especially for the kids.
