Disagree with your underlying assertion that students do not read nonfiction books. Your textbooks are nonfiction.
In terms of more “classic” nonfiction materials, j don’t think it’s a very important skill. Something like Anne Frank’s diary or Night can definitely be powerful, but I don’t think reading a secondary source on the American civil war has any more value for a student than a chapter in a textbook.
Nice bar: whatever menu cocktail or specialty product looks good.
Okay bar: Amaro/mezcal if they have it, gin/rum if they don’t.
Not very good bar: beer or cider
Bad bar: bottle beer. No cans, mixers, or taps, and well pours only if truly desperate.
