I've tapped out the great choices in ready-to-eat foods at the mid-Peninsula farmers markets where I live -- killer sorbet, great crepes, Indian yummies and on and on like that -- so my friends and I want to branch out. What are the best markets for such stuff? Ferry Plaza is great, of course. And I've heard that Grand Lake and maybe Temescal are very good. Any other suggestions? And are there any that should be skipped -- like Mountain View -- because the local eateries but the kabosh on such competition? And finally, what vendors at these markets shouldn't be missed?
