Cities existing on a regular grid pattern is certainly not unique to Chicago.
For example, I'll give you my own hometown of Tulsa. Our street system is an engineer's dream.
The streets are laid out on a perfectly north-south/east west grid pattern, with arterial streets exactly one mile apart each. The east-west streets are all numbered, and each number is 1/10th of a mile (on occasions where more than one is required in that tenth of a mile, the extra street will be labeled "nth place" rather than the typical "nth street".) Sadly, the north-south streets had to have names, but even there the ones east of downtown are named after cities east of the Mississippi, and the ones west of downtown are named after cities west of the Mississippi.
The implication of this is that all a person has to do is memorize the names and order of the north-south arteries, and they know how to go anywhere in Tulsa, and how far any two points are from each other.
In theory this also means the Tulsa grid system applies to the entire earth (although globe projections would be a problem near the poles). Some wags have used this fact to set up a monument at our 0 point named "Center of the Universe".
I'm not saying all this to try to claim Tulsa is in fact more regular. I've no doubt that this is a quite common feature of newer 20th Century-designed cities, particularly in the US. What I'm doing is pointing out that the regular city grid is not unique to Chicago.
