This second season had an overarching plot, unlike the first season.
You could probably understand most of what's happening without knowing the first season but I'd recommend watching season 1 first, as the regular customers are I introduced there.

The food, the acting, and the general atmosphere ware delightful again.

There are a few minor things that made me subtract half a point:
* I felt that in season 1 the customers interacted a bit more. The Izakaya felt emptier and not as lively. In season 1 it felt like a centre of a community.
* It felt like the food had less variety? I'm not sure why though.
* The hairstyle of some characters looked more anime-ish than in season 1.
* I missed the characters from before, especially Nikolaus. But I liked how they gently wrote most characters out and did not just let them disappear.

Overall, another mouth-watering, light and mostly fluffy series, a great watch if you just need a diversion from the Real World.
