Hackney's/Flaco's Owners to Open Ice Cream Shop in Printers Row?

A reader writes:

The brothers who own Flaco's Tacos and Hackney's on S. Dearborn b/t Polk & Harrison have acquired Castle Keepers, the real estate office that was in between the two businesses, and say they're putting in an ice cream shop. Don't know the timetable, but will keep you posted.

Seems like an amazing addition to Printer's Row.  And given the track record of Hackney's and Flaco's, we are optimistic.

Standalone ice cream shops in the Sloop have been elusive.  Back in February of 2012, Marble Slab Ice Creamery closed up shop at 1241 S. Michigan.  Outside of that, you can get Ice Cream in the neighborhood, but tends to be as a dessert at a restaurant or a secondary offering.

The closest we have would be Baskin Robins (1231 S. Wabash).  Or you could get Gelato at Little Branch (1251 S. Prairie), Artist's Cafe (1150 S. Wabash), Stan's Donuts (26 E. Roosevelt) or frozen yogurt at Chicago Kernel (511 S. State).  Obviously there are more, but these stand out.

So what do you think?  Will they succeed?
