This Japanese restaurant offers puzzles and coded menus! The puzzles rely on a coded-language tradition called goroawase, so if you know a little Japanese, they are sure to raise anticipation. Counter seating, which affords a view of the food-preparation process, adds a touch of fun as well. The eatery’s name can mean ‘leaving the nest’, and indeed the young cooks create a cheerful atmosphere. Puzzle-solving is for evenings only; lunch is traditional kaiseki, finishing with sea bream rice with green tea poured over it.
