Chris,
I'm glad you're still reading. I've enjoyed the episodes so far and I just watched the Chicago show. Overall, I liked it, but as a Chicagoan passionate about our food culture, I feel the need to dissect the show a little bit

(respectfully and constructively, of course).
--As much of a media darling as it is, I think Hot Doug's is a must and I'm glad you went there. It's far enough away that your average tourist won't make it there. Doug is a terrific guy and the place is really good on camera. He does great stuff and deserves tons of praise and exposure for his addition to the Chicago sausage scene.
--I grew up with
Myron & Phil's as one of my family's special event restaurants (it remains as such today). It's got a lot of charm and I'm glad you went there instead of the more famous places. I'm slightly disappointed that you didn't mention the chopped liver (and the overall Jewish heritage of the place).
--Greektown is fun, but for an ethnic neighborhood I'd have skipped it in favor of Devon Ave., our teeming Indo-Pak neighborhood (much east of Myron & Phil's). Thinking back to previous episodes, you already went to the Bangladeshi place in Atlanta (my favorite episode), so I understand the producers wanting to keep a good mix.
--Calvin's. Eh. There is much better off-the-beaten path BBQ in Chicago. Although the spaghetti was cool for TV.
--You must know that when you were at Gino's, you were eating in one of the biggest touristy neighborhoods in town. I love deep-dish pizza as much as the next Chicagoan, and I think Gino's is a terrible example of it. Next time, Lou Malnati's (you could've walked to the original from Myron & Phil's).
--As someone who is involved in more than one Chicago-oriented food website, seeing GrubHub (a food delivery menu guide) represent us got my hackles up a little. Can you blame me?
Overall, I enjoyed the show and I look forward to your future episodes. If you're ever in Chicago again, with or without TV cameras, please let us know. We'll show you some great spots that are not nearly photogenic enough for The Food Network.
Best,
Michael
