Sure is (first link has the address). I was there once around '09/'10 for a tour and only remember them showing 2-3 floors which, again from what I remember, was the shared colocation space at the time. IIRC at least one floor was newly built out and barely occupied. We signed with them and I never had to go inside again.
As far as Chicago goes from what I remember someone at the company had a bad experience with DRT so we never looked at 600 S Federal but we did look at Equinix at 350 E Cermak (which REALLY stands out) and a handful of others that weren't memorable.

Thanks for the added detail!
