In about a week, I will start a new job located at Walnut Creek (2121 California) near the BART station. I would like to know what are some lunch options around there. I'm looking for sandwiches and hot/cold food bars, something like Delessio or Foccacia Cafe in SF. Most likely, I will not have a car so within walking distances would be good.
My new job also requires field work at the Oakland Main Postal Facility near the West Oakland BART station. I would also like to know what are the options around there for the same criteria above. I'm not sure if I will be driving there yet so recommendations for walking and driving distances would be appreciated.
