Any of the Ghibli movies? Have you seen the food they have? Aside of that joke …
It is really hard to decide. Marvel universe would be interesting because you just get superpowers basically by default.
None of the classic animes. They are too focused on the main characters to have any meaningful world building.
Star Trek during TNG is very chill for the masses. So that would be safe and interesting.
None of the SW bs, no Harry Potter neither… Maybe some Forgotten Realms stuff - probably after the Drizzt saga (i stooped reading after the 5k orcs books so probably arond there).
Dragonlance had a nice idillic world building. And they had dragons!
Very hard question, indeed!

‘Theater partner’ is literal translation. Basically it is her date for an actual theater performance.
The implications is that going to a theater or opera means you have to dress up. It was still true about 30 years ago.
The basket and wallet indicates that she thinks he is dressed for a date to go to the piac (kinda farmer’s market but not fancy at all think of fish market just no fish).
