35 E. 18th St.
Helmed by Michelin star Chef Jean-Georges Vongerichten, ABC Kitchen has been one of the most buzzed-about restaurants in the Flatiron since it opened in 2010.
The restaurant serves a menu that is "free of pesticides, synthetic fertilizers, insecticides, antibiotics, hormones," and more. The menu changes but always features fresh, local, and organic ingredients.
