While Chicago has a rather impressive ethnic food supply, and some pretty serious american food (Pizza, Italian Beef, etc.) I have on the whole been very unhappy with my food options in Chicago.
No real mexican food, No BBQ to speak of, and the only seafood that was good was expensive.
Now I'm back on the Central coast of California. I've had burritos at what I think is the best burrito bar on the planet...and I'm back to thinking that Chipotle is a form of toxic waste packaged into a burrito form, because I can now eat the real thing. While I can't suggest that we've got decent BBQ here, we do have good, cheap seafood, what with being on the ocean...and we also have a phenomenal, heavily non-paleo selection of excellent sandwich shops, and the local, high-quality versions of both wraps and California Pizza Kitchen.
Sure, my Indian/Greek/Ethiopian food options have been massively curtailed, but what this place is good at it's great at. Happy to be home.
