Del Taco in Chicago (via Levy restaurants)

While searching for carne asada | steak burritos, a search of here turned up nothing about this. Strange, when you contemplate we have a thread about Levy buying the Wiener's Circle. (A general Google search found it.) The Orange County Register reported (back in March) Del Taco sold to Levy Acquisitions.

When I lived in southern California in 1981-82, Del Taco was one of my favorite fast food stands. The piece mentions when it bought Naugles. I recall a Naugles on the southeast corner of Addison & Western. It may have actually converted to a Del Taco for awhile. But obviously it isn't one now.
Does anybody here have more details on the progress of this operation? I would think we would have heard rumors of potential locations by now.
