A nine-floor architectural wonder with a soaring glass atrium, semi-spiral escalators, and majestic domed roof, the Westfield Shopping Centre is an enormous consumer mecca at the border of Union Square and SoMa. Nordstrom's anchors the top five levels but there's also a Bloomingdales, Zara, Club Monaco, and other high-end chain retail. The basement level provides access to the Powell Street BART station.
