The San Francisco Bay Area Restaurants Survey is more than just a list of winners. Sure, we love to know who got Top Food honors, who's the Best Newcomer and who offers the Best Bang for The Buck, but with 1,636 restaurants rated and reviewed in the new guide, the data offers meaningful insight to the local Nor Cal dining scene as a whole. Here's an inside analysis on who's up and down in the 2013 guide. What were the biggest surprises for you? Be sure to let us know your thoughts about the results in the comments, or via Google+ and Twitter using the hashtag #ZagatSF2013.
