A friend of mine just flew from ORD - CPH - ZRH after a long drive down from Traverse City and found a place to nap - in the new ORD wing of Terminal 5. He said he caught a good 90 minutes of slumber. I guess there's nothing there yet but a few chair banks, relatively clean carpet. Said it was hard to find a working outlet to charge his phone, though.
