Just letting you know i got a tip from someone about the new owners at 1212 S. Michigan.
A new snap fitness is going in there, complete with pool:
http://www.snapfitness.com/southloop I was also told that they're trying to open up this corner above the subway so people can exercise and look out over grant park and the lake.
Apparently the new owner has some pretty big plans for this building, to update it and make it fit in with the level of finish for the rest of the stuff in the south loop.
Last item i heard, the owners of the columbian have gotten a lot of interest but they refuse to subdivide or alter the 2 spaces they're marketing which is turning quite a few potential tenants away. Also, they're asking for too much in rent compared to neighboring buildings.
