Foodies and NYC historians descend en masse on uptown bookstore Book Culture (formerly, and forever in some hearts, known as Labyrinth) tonight to hear from the two editors of Gastropolis, an in-depth look at New York's food heritage. If their guesting stint at the Times was any indication, experts Annie Hauck-Lawson and Jonathan Deutsch will shed plenty of light on everything from egg creams to pupusas. A bonus: there's a tasting following the reading.
