You know, I've always found Chicago to be a *good* coffee town. No, it's not Seattle, where the stuff is taken as seriously as they say (wish it were as so with seafood, an area that suprised me as good but not as good as it should be, but that's a different story) nor is it South Florida or South Louisiana where Cuban and French styles held forth long before the Italophiles of the Northwest came along in the 70's. But solid. Apparently, the geniuses at Starbucks decided that Chicago had the capacity, taste, and weather for better-than-7-11 coffee when they decided to use our town as the platform for world domination (Chicago being the "second market" for the co., way before expansion to even CA -- original stores are Hyde Park and Randolph/Wacker).
So, I wouldn't think that Chicago should be singled out for bad coffee.
PS, it might not be obvious, given where you live, but there is some kind of double-reverse post-colonial exchange thing going on with Vietnamese cafes. I've never had the pleasure of visiting Vietnam, but every time I've had coffee at a Vietnamese place (the black is very similar to Cuban coffee in its prep and sugar content), they use Cafe Du Monde, right from the goldenrod can. Consistent in IL, CA, FL, etc. If nothing else, you ban go to Ba Le here and get your strong NO coffee fix anytime.
