Like your typical Barnes & Noble store, you can find almost any book you might be looking for here. They've got many magazines, and a pretty good selection of music (overpriced in my opinion though)
The location is very convenient, as it is located in the Potomac Yard shopping center right on Route 1 (Jefferson Davis Highway). There usually is more than enough parking. The staff is extremely friendly, and the best part is that it's open until 11 pm! And, if you want to grab a cup of coffee and read a book, there's a coffee shop right in the store!
