One word ... Classic. This is the best word I could define this anime. Art, music, characters, the introduction, animation (3D art was done very well, no flaws). First episode was very good, the second episode was a blow out ... Very interesting, indeed.
It's about a very young girl (yearly 20s), falling in love with an older man (35+) ... so far. Tho' the story revolves around a tiny famous restaurant with male servants of 35+ year old, each. Very classic.
