Burger King's "abdication" of the Loop?

From Cecil’s Mail:

They were all owned by Ameriking, a big franchisee that had a big chunk of the Chicago market. Ameriking went into bankruptcy about three years ago. I don’t know what the story is at the Thompson Center, nor do I know why no other franchisee has reestablished any downtown locations.

I miss them, though. There’s nothing like flame-broiled.
