Have you been to More Books, around the corner from the Powell's on Hawthorne? They don't want you to use your cellphone, are anti-wifi, only accept cash and use a handwritten ledger - all of which I find quite charming in a bookstore.

They had a ~100 year old typewritten compilation of translated Chinese sex jokes.

Not much fantasy/sci-fi but if you like books it's got a real 'living my best life in my bookstore' kind of vibe that you might enjoy.
