Why aren't there more Hot Food Push Carts/Stands in Chicago?  Are the laws/regulations so much stiffer here than in New York?  Other than the Elotes salesmen in the parks, I can't think of seeing other hot foods being sold by carts.  I do see quite a few "Roach Coaches" on the street and downtown at lunchtime.  I looked at the city's website and didn't see anything specific on the topic.  I think they add a lot to the character of Manhattan and serve a pretty darn good dog, occasional soggy bun notwithstanding.  When I was younger, I do remember seeing more of them in Chicago, but people also died much younger back then, too....
Just curious
