I really might love you.
As if the writing style itself weren't fully endearing, your characterizations are beyond my scope of praise. Your Iruka blows me away, especially, and you Kakashi is just... Kakashi!
There are too many beautiful parts of this fic for me to condense it into a list, but I do love the restaraunt as a whole.
The only thing that comes close to an issue: Ibiki is a special jounin, which is something of a glorified chuunin. Why would he frequent an establishment for high-level jounin? (Not that it doesn't totally suit him)
