Mysterious Brown Paper on the Windows of Old Grant Park Cleaners (State & Roosevelt)

The mysterious brown paper has now gone up on the windows at the little retail building at the corner of State and Roosevelt (3 E. State).  This was the old space of Grant Park Cleaners, which closed last year.

It's some primo real estate and seems perfect for a coffee shop or some sort of convenient food joint.  We're not sure if this means that something is coming or if the owners simply put this up so peepers don't creep on the space.  

Anyone have insight?

This seems like a big opportunity for this intersection.  If they could get a good tenant, it would really be a boon for this intersection.  In our opinion this stretch of State street is really lacking compared to Wabash which seems to continually get better.
