This is a 350,000 square-foot entertainment complex that is basically a showcase for Sony products, music, and accessories. I’ve read mixed reviews about the place and in speaking to several Bay Area locals, they told me that it was an economic boondongle.
Regardless, I am a long time admirer of Sony- it’s design and innovation, especially in video and consumer electronics. This is a good place to go if you want to see the full range of Sony products, but I would not recommend buying anything there. Shop there for selection, but buy on the Net from places like Amazon or brick and mortar stores like Best Buy for price.
