I'm currently 15 months into an SF lease for my company and when I originally looked for space I spent a lot of time looking in Oakland thinking I'd get a lot greater value. Unfortunately I found only one nice "SOMA style" space in Oakland it was right on the edge of Chinatown in an area I'm not sure I'd want female employees walking to BART late at night.
Honestly there's a huge opportunity here for some developers to look at building out some nicer office spaces in Oldtown, Jack London or the Grand/Broadway area near 19th St BART. I don't mean stuff thats gorgeous just something slightly contemporary would be an upgrade.
