I want to know the answer to the following question:
What is the biggest office building in Tucson?
All the background I'm provided with is that "Restaurant Row is sandwiched by three of Tucson's storied Neighborhoods: Harold Bell Wright Estates, named after the famous author's ranch which occupied some of that area prior to the depression; the Tucson Country Club (the third to bear the name Tucson Country Club), and the Dorado Country Club.". Is that enough to answer the question?
