I'm not sure what connotations the word こじゃれる has in Japanese (it's not in many dictionaries). I decided to translate it with the old-fashioned word "groovy."
I've have translated the word コーナー as "section", don't know if there's a better word for it.
I thought about how to translate this for a very long time.
There doesn't seem to be an English idiom with the word "cut" in it that would fit here, so that what Morikubo says next makes sense without a note.
