Look at the map again, over on the far left side, almost at the edge of the map, just south of Main Street and you'll see #37. It's faint and tough to see, I had to go to full zoom. This matches the 1600 S. Main street address.
The location you're refering to on the north side of State St must be 31. When I was a kid the State Theatre was there, and now it's a high rise for seniors, the Luther Center. It also houses the N. Illinois Synod offices for the Evangelical Luthern Church.
The bottom line, however, is that the distillery is no longer there
