I work right across the street from it - seeing it come down right now, but I've always thought the building had great bones and a good look.  I wish it could have been upgraded and re-purposed, seems like such a waste of energy to tear it all down to (hopefully) build something back up....I really hope it doesn't remain an empty lot for years, or a parking lot, too much underdeveloped property in midtown as it is.  It's in a great walkable area with a good bus line, so I'll hope for a super energy efficient mixed used building without a big sea of parking.
