If you can ignore the loud loungy-house music and the juicing/blending - then this is a decent place to work. I'm always able to find a spot to work here.

Your average Peets Coffee - kind of loud, kind of crowded, kind of dirty.

Common Sage is an asian convenience store / Korean restaurant / cafe. Most people come here for a quick bite or to people watch on Polk Street - but they do have wifi and plenty of table space for a work session.
