There's a Fogo de Chao (Brazilian Steakhouse) behind the Double Tree Hotel. For those who aren't familiar with this type of resturaunt it is all u can eat steak, a variety to choose from too, but not just steak they have other meat too like chicken and lamb and a big salad bar (never tried it). They come around with hunks of meat on spickets and cut you off pieces. You get what looks like a drink coaster that's red on one side and green on the other...as long as the green side is up they keep bringing food until you turn the coaster to the red side up. The first time I tried this restaurant was in Brazil and have hit up several in the states since then. It is expensive probably ~$45 for dinner, however I've found out that lunch is ~$25 and serves the same items. Not sure of the etiquette in Chicago but in Brazil they let you sit there for hours flipping your coaster.
You should also try a Caipirinha, which is Brazil's national cocktail made with cachaça.
