Me loves the Steak and Shake. In fact, I ate lunch there yesterday at the downtown Indy location. Triple XXX in West Lafayette is pretty decent too. 96th Street steakburger in Indy is kind of like In and Out I guess. the menu is basically burgers, and they are fresh and tasty. I used to eat there for lunch quite a bit when I worked on the north side.
I grew up in Iowa and we didn't go to McDonalds, we went to Mr. Quick's which was a regional burger chain. Sadly, they went out of business quite a while ago, and I think all of the independents have closed as well. My bro and I used to split their "5 burgers and 1/2lb of fries for $5 deal.
