Swap-O-Rama Replaces CSI at 1725 S. Michigan

A reader writes:

So we woke up a couple of days ago to learn that CSI had left and this new business had moved in. Seeing people come in and out though we haven't gone to investigate yet. Surprised this would move in here (1725 S Michigan Ave) and wonder its impact on our neighborhood.

For those who aren't familiar with this building here is a shot from google maps.  It's on the east side of Michigan avenue and right across the street from South Loop Market (so very close to the intersection of 18th and Michigan).

We've heard of Swap-o-Rama but have never been.  Thoughts?  Has anyone been to this one or another?
