However, it's about as hard as it is for the SF Downtown <-> South Bay connection, since to get to Downtown from CalTrain, you have to pass by a BART station :-)

A few coffee shops, grocers and startups and I think the area could rapidly transform.
There's lots of art stuff happening, but no tech/internet (which isn't that surprising).
