HIGHLY recommend the Chicago Pizza Tour! I have been taking my students on this tour for 8 years now, Jonathan Porter and Jonathan Knotek do an amazing job! Jonathan Knotek who has been our tour guide each time is great with people, super friendly and his knowledge of Chicago runs deeps! You can tell these guys got into a business they love! The history, the food and experience is phenomenal, I could not recommend this more. You truly get to experience so many different styles of pizza and how those pizzas came about. What a great tour, which is why we go back every year!
