Best indoor mall/shopping center in San Francisco ...

Best indoor mall/shopping center in San Francisco located on Market Street (the main street of SF) and across the street from the start of the Powell Street cable car line. Just a few blocks from both Union Square and the Moscone center. Multi-level building with a circular foyer in the center. Way more interesting from an architectural standpoint than most malls to say the least. Also home to the best multo-screen movie theater in SF, the Century.
