Found this hotel-level site through their Facebook page:http://www.cambriadallas.com
No menu yet listed for their bistro. A few of the hotel amenities are listed; there are 177 rooms on 23 floors.
Tried their phone # (214/220-2900) and no answer... busy? not by the phone?
The hotel's Choice Hotels site is taking reservations (most rates around $117) but on-site pictures don't seem to have been updated there.
There is a TripAdvisor site for the Cambria, but no one has posted any stay opinions or green buttons (like stars on other sites) yet.
