This place saved me from heat stroke many a time in college when I had no ac in my house. Id hike over here to beat the heat for a few hours on steamy July days. Actually it's so nice inside I kind of got excited to study cause I knew I'd have an excuse to hang out at one of the epic long tables inside and look up at the marble ceilings.
Aside from how aesthetically pleasing it is, you can rent pretty much any tv show, movie and cd that's out. If they don't have what you want, they will also order it for you, just be patient it might take a month or so. Also the late fees are super reasonable and you can check out like 30 things at once.
PS good people watching inside.
