Tom Sietsema's dining guides aren't static lists. Twice a year, The Post's food critic puts together a collection of the places you should visit. While the spring guide revisits previously reviewed eateries, the fall version features his top picks for the best of the best.

So who's in? Who's out? Who gained stars, and who lost them? With more than 50 restaurants in this year's fall guide, there's more data than ever to analyze. Here are some of the more noteworthy observations.

51 star-rated restaurants in this year's fall guide, compared to 37 in 2015. (One in this year's fall guide, Sweet Home Cafe, hasn't been rated yet. Peter Chang's two locations are counted individually.)
