I posted this question a few months ago and got only one reply but the responder wasn't really sure. Here's one more try.

A few years ago I was in Chicago and visited a really great LBS. It was three floors and the top floor had folders and a small indoor track you could ride around. The people were really nice too. I can't remember the name and location. I just know that it was walking distance (long walking distance I think) from the Drake Hotel.

I'll be back in Chicago in two weeks and would like to stop in again. Any help please. Thanks.
