OK I am a poor teacher, and I like to go to Barnes & Noble to read yet not buy. I'm not a good customer, though every once in a great while I'll buy something. I love to go there, grab a ton of magazines, go upstairs, and read until I can't stand it anymore. You are allowed to bring drinks in, which is great, so you can drink while you read. I have read several books there in their comfy chairs, which you can move to face out the large windows. B&N is generally expensive, but they do have sale tables where some super deals can be had. Their customer service is top notch, they will special order for you (I've done this for school before, and it's a great help!) and it's free if you get it delivered to the store; a little more if you want it to go to your house. In general, I like the place, I just think it's too expensive. But I love the atmosphere!
PROS: Big Chairs, great selection
CONS: too pricey
