I think it’s mostly for clarity and accuracy’s sake. These are real drinks and desserts that are referenced throughout the story, and as a person interested in the topic of coffee I’ve found the use of the same names very nice. Especially now I can look up those drinks and maybe even make them myself (▰˘◡˘▰)
well i do think like its a thanos speaking english situation to make it easier for audiences but its always funny in my head that what if i knew someone and she pulled naming a strange drink 'latte' when maybe latte already means something else in that world or is just a buncha nonsensical words lmao its just funny
if i had carried over a practical/inventive skill into a period world id name them with something else cause why is she still carrying italian words in a world where maybe theres no italy i mean itd be funny to makeup new names for these coffees plus since characters dont know what genre their story is, what if its thriller and by keeping foreign never-heard-before words youre sending a beacon to others who is also isekaid or is hunting isekaid people idk.....ive read too many isekai i start thinking about technicalities lmao
