I like Barnes & Noble when it comes to big book stores; but in Dade City, FL we have a small book store called the Book Shack where you can trade in books and its actually my favorite place to buy/trade books. http://www.recklesskelly.com
I once went to this wicked book store/cafe thing in Winnipeg, Manitoba... at least, i think it was Winnipeg... places run together sometimes. It was a used bookstore, run by a family who lived above the shop. It had a cafe that served homemade food and drinks, old couches and chairs and coffee tables to sit in. Had a stage in the corner for jamming and such. You could come in, trade or buy a book, get something to eat (they had veggie options too), and read until the live music started. and that, my friends, was the best bookstore in the world.
