Even if you don't want to spend your life savings at all of the stores on Michigan Ave, there are definitely some really interesting things on the street you probably don't have at home. There are beautiful statues, gardens, parks, immense sky scrapers with some really gorgeous architecture, and some really interesting people. It's great for sight seeing and this is the place to be if you want to feel like you are in the big city of Chicago.
Be aware- a lot of homeless do hang out on the street and "Apple Pickers" if you're eating at one of the outdoor areas someone may approach you with a flyer or something like that-this is Apple (iphones, apple products) Picking. They put their flyer your phone and take your phone without you realizing it. More
