Sutro Project / San Francisco Centre
San Francisco's primary upscale shopping location. Stonestown Galleria is the only other mall within the city, and it's much smaller.
Union Square is a couple blocks up Powell and augments with a variety of high-end and boutique stores.
The food court is on the bottom floor with surprisingly diverse and tasty provisions.
And hey, it's still in San Francisco :)
