Ontario Street - fast food gulch?

 We recently wrote about the owners of the old Museum of Contemporary Art hoping to chop it up into several different fast food facilities.  Now comes word from Crain's Chicago Business that their neighbor, the recently abandoned  U.S. Post Office, has been purchased for $5.9 million by a firm that proposes to do exactly the same thing.  In no time flat, we could be seeing a festival of up to eight more junk food outlets one after another, like pins in a bowling alley, just with a lot more calories and fat.
