On the 9th floor of the Harold Washington Library in the loop, you can find a beautiful atrium for a study space.  The Winter Garden's glass roof offer gorgeous, abundant, and natural light all year round despite the temperamental weather outside. It's one of my favorite places to finally get things on my to-do list done as the space offers a delightful illusion of an urban courtyard with its natural light and olive trees (not to mention stunning views of the surrounding city). It's open during normal library hours so who knows, maybe I'll run into you there sometime this week!
