Not really a question about traveling itself, but thought I could ask for some help. I'm scheduled to visit the US in about a week or so, and wanted to pay a visit to some bookstores if I can. In case you're wondering, I'll be visiting San Francisco, Las Vegas, and Los Angeles.
The particular bookstores that I have in mind are those that are large enough to hold a variety of books, including textbooks (usually books used from the university-level and upwards). My home country of Korea has a company that is known for operating very large bookstores (Kyobo in case anyone's wondering) and this store sells books from fiction, nonfiction, hobby, high school textbooks, foreign books, college textbooks, test preparation books, etc.
I was wondering if there would be stores of that caliber in the places I visit. Any tips are appreciated. Thanks in advance.
