Former ballerina/nutrition expert/collector of fine things Mihoko Kiyokawa brings Franco-Japanese fare to the Flatiron. Tall ceilings, vivid artwork, gold-and-tan embroidered screens fill intimate dining room. Two- and three-course dinner menus highlighted by fluke tartare, buckwheat pasta with pork belly, king salmon with Japanese eggplant. Sushi bar as well. Name comes from Dr. Douglas MacDougall’s 1901 appraisal of the weight of a human soul, but your mileage may vary.
