The Lincoln Park Conservatory is a little gem along the lake in a beautiful part of the city. It's a nice little escape from all the buildings and skyscrapers, though those are of course enjoyable in their own right. The conservatory offers a more serene setting to escape the hustle and bustle of city life, a great place to go with a friend or alone, just to think. Outside of the conservatory is a large field with a great view of Chicago's skyline, perfect for a picnic or some meditation. And the best part is it's free, and close to the zoo and a cute little landscaped lily pond which I discovered happily by accident on my way. Definitely worth a trip if you haven't already been there.
