Saka Gura is one of my faves. I should point out that they used to have killer lichee sake martinis. Alas, they are no longer being served. This may also be the case with the bourbon. They may only be serving sake now. A funny Saka Gura story, the guard for the office building told me that it isn't uncommon for drunk Japanese ex-pats to bang into the faux-marble walls in the lobby, bow to the wall and say "so sorry, so sorry".
