You could get lost for hours reviewing the library of sake bottles lining the wooden shelves that run from floor to ceiling at Fuku. The menu provides a map to help you navigate the range, which stretches all the way from an enjoyable Hakutsuru warm sake from Kobu ($10) to a Born Junmai Daiginjo from the Fukui region ($175).
To ensure you have ample time to find the wisdom at the bottom of the bottle, you'll want to settle down for dinner. Highlights include smoked miso-marinated black cod ($16), presented with a dramatic flourish in its still-burning embers, and a twice-cooked duck breast served in soft slices with a sweet persimmon puree and yuzu pepper jus. A hidden haven from the bustle of World Square, Fuku is an ideal spot for a quiet catch-up with good friends and a serious boost to your sake education.
