Diablo Foods in Lafayette? Lunardi's in Walnut Creek or Danville?Interesting. I would have expected a place like that here in the East SFBA, but I haven't heard of any.
There's also Market Hall Produce in the Rockridge district of Oakland but they can be inconsistent. Monterey Market in north Berkeley. And, of course, there's the world famous Berkeley Bowl in, you guessed it, Berkeley - and it can be a zoo!
