So sorry for not following up on this quickly.
For one, make sure you check out Bourdain's other episodes about Chicago. There was a No Reservations episode that is not fantastic, but still pretty worthwhile https://www.dailymotion.com/video/x2ifwlz
There was also an episode of The Layover that had a lot of fun suggestions.
Grant Achatz (the guy behind Alinea and a couple other great Chicago restaurants) had an entire episode of the Netflix series Chef's Table dedicated to his work and it's pretty great.
A Tribune writer wrote a book about the brief Foie Gras ban that happened in Chicago about a decade ago. I found it really interesting https://www.amazon.com/Foie-Gras-Wars-000-Year-Old-Delicacy/dp/1451640862
The Eater has a bunch of really useful map based lists of restaurants and such. I use it all the time to find new restaurants to try and when I'm giving restaurant recommendations on here and to family. https://chicago.eater.com/2018/1/5/16151978/best-food-chicago-restaurants-city-guide
