Lea Michele presents her new book, ‘Brunette Ambition,’ with special guest Jonathan Groff

Tenement Talks: ‘Urban Appetites’

It’s no coincidence that our city’s nicknamed “The Big Apple,” because we New Yorkers have an appetite for life and for food. At this edition of the Tenement Museum’s Tenement Talks, author Cindy R. Lobel will be joined by notable foodies to talk about present-day food markets and the state of food in NYC, as well as Lobel’s new book, “Urban Appetites,” which details the history of 19th century food and culture in NYC.
