If you have never been to "The Bean" it should definitely be on your list. Located in the heart of Chicago, it sits next to Lake Michigan, The Art Institute of Chicago (where Rohan went to school), The Field Museum, and many other attractions. Best of all, ITS FREE!
If you have never had Deep Dish pizza, I would recommend trying it. Not for everyone, but an experience you can brag about to your friends.
Great restaurant with solid Gluten-Free options.
