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 and maki 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.
