U.S. Bank Tower, the tallest building in the West, will soon have an observation deck and a sky-high restaurant.  The 72 story skyscraper, completed in 1989, will remain an office building, but it will get about $50 million worth of improvements, including a makeover of the lobby.  Plans are underway to build an observation deck on the 69th and 70th floors, and a restaurant on the 71st floor.

It is estimated that the observation deck could attract 500,000 people per year, each of whom would pay around $25 for entry.
