I think the argument could be made that during the last cycle, River North actually had MORE development than the West Loop had. It's just not as noticeable because the it's not the same type of transformation. What River North doesn't have is 800 proposals waiting to kick off.
-One Chicago
-Two Chicago (not sure it's actually called this)
-Wolf Point South, East, West
-The Hudson
-Superior House
-400 W Huron
-360 W Erie
-The Ronsley
-Hubbard 221
-311 Illinois
-Gallery On Wells
-640 N Wells
-Exhibit on Superior
-The Bentham
-The Ardus
-Home2Suites Hotel
-Moxy Hotel
-369 W Grand (Omni?)
-490 N Lasalle Office Building
-The Marlowe
-Oh, and the McDonalds has solar panels now.
Not to make it a competition, but I don't think the West Loop really matches all of that.
