This is hands down, my favorite bookstore. I think they padded the wooden floors somehow because I swear it was such a comfortable browsing experience that I stayed a few hours! Also, they will find anything you're looking for. Terrific poetry section as well.
This interactive sidewalk street art installation is super strange and random. I wouldn't go out of my way to see it, but if you happen to be in the area, it's cool to see. It's within walking distance of a Voodoo Doughnut.
