I have heard people talking about there are no toy store in downtown. There was a couple a few years ago but they have been closed. We went to the Bloomingdales (900 N. Michigan) last weekend and found a baby store on the fifth floor, it was not very big, but have quite a few things, especially have lots of strollers. It is called Galt. Also, we have a website that you could come to visit and find some strollers through Amazon:

Baby Strollers

Let me know if you find the price is reasonable.
