As a former Kaiser worker, now working in SF, I have recently been making a trip every now and then into Oakland for lunch via BART to connect with my old lunch cronies. It has spurred me to re-publicize my Oakland Food Chart to those who haven't seen it yet. I have also enlisted the assistance of my contacts still in Oakland to keep the reviews fresh and welcome any submissions from others. My hope is that you might enjoy a meal you never would have had (or avoid a bad one).
Long Live the Oakland Luncher. You make me proud to have worked in your town.
