On the Left Bank, on Quai Voltaire, this new sushi restaurant is hidden behind a discreet black façade without a sign, simply bearing the number 15. Inside, Masayoshi Hanada (formerly at Sushi B) builds a single omakase menu around exceptional fish – Mediterranean bluefin tuna, Auvergne trout, catch from Brittany – absolutely masterfully cut and prepared. Affording a view of the chef and his assistants meticulously going about their tasks, the superb solid hinoki (Japanese cypress) counter seats just 10 guests. Finely crafted nigiri, maki, soups and binchotan-grilled dishes are served on refined tableware at the intersection of tradition and contemporary design. A short wine list and nine types of sake round off this memorable and special experience.
