Writer and public health activist Marion Nestle drops by CQ Roll Call HQ tonight for the finale of 2013’s Roll Call Book Club. She’ll be discussing her latest book, “Eat Drink Vote,” a brisk and funny read about food politics that helps make its message with political cartoons.

So drop by for some wine, some cheese and a free copy of the book. Roll Call resident food maven Warren Rojas will introduce Nestle, who apparently has a few things to say about how, why and what we stuff in our mouths.

Free, at 77 K St. NE from 6 p.m. to about 8 p.m.
