I love reading and books, so Barnes and Noble is my type of place. They have a huge selection and they are always having clearance tables where you can find older books for only a few dollars. They have comfy chairs in a bunch of different areas so they don't mind if you sit and look at books to see if you want to buy them. Or you can go into the little starbucks counter that they have and get a coffee or a snack- they have cookies and cheesecake and all kinds of fancy goodies.
They also have a wonderful children's area. Huge book selection and also some neat stuffed animals and toys. They have a train table that my daughter loves to play with.
You can spend a good few hours here at Barnes and Noble looking through books if you want. The staff is always great and will do whatever they can to help you.
