Chicago’s Secret Interiors walking tour mixes skyline highlights with rarely seen lobbies, domes, and gardens, led by a small expert group.

“We've used Viator when traveling in Europe and would have never thought to use them locally. But we did and so happy we did! Our tour guide, Ethan, was awesome. We had a huge group (40 people) and he handled the group perfectly with great enthusiasm, making sure we were always together, that we could hear him, etc. And he was super knowledgeable. Even living in Chicago our whole lives, we learned so much. Highly recommend.”
