Chefs Riad Nasr and Lee Hanson worked on Keith McNally restaurants—Balthazar, Pastis, et al—for 16 years before deciding to venture out on their own. Frenchette, named for a 1978 David Johansen song. It’s a beauty. The gleaming wood paneling, the zinc bar, the leather banquettes, the Art Moderne curves…. It’s an idealized vision of a bistro that calls to mind a McNally restaurant. That’s sort of the idea, and not at all the idea: They want to build on what they’ve learned about food, service, and design. Frenchette is currently open for dinner and weekday lunch.
