There aren't any 2 story retail spaces left on the Square. The only options would have been across the street in the Westin, and/or USBank. I doubt the two story Skyline is legit. I'm not sure where it would go. On the 6th street side of the 5/3rd/Rock Bottom building there is a parking garage on the 2nd level.
3 Skyline's downtown is actually alot...
