Chicago is a world leader in Starbucks, even if it is sometimes insecure about its place on the world stage:

Chicago is home to 164 Starbucks, ranking the city second in the United State behind New York City–and fifth in the world, according to Starbucks store data compiled by Chris Meller.

There are 64 locations in an area bounded by DesPlaines, Oak Street, Congress Parkway and Navy Pier. That’s 40 percent of the city’s total…

At O’Hare International Airport alone, there are 17 Starbucks locations, including spots in baggage claims, terminal concourses, food courts and near gates.

The South Side has only nine stores south of 33rd Street. There are no Starbucks on the West Side–at least none west of Ashland.

The common factors behind the Chicago locations seem to be the wealth and number of tourists in different locations. In other words, Starbucks tends to locate where there are more people with more money to spend on coffee. This may be a little different than the vision the store promotes for serving as a “third place” – these third places are for certain kinds of neighborhoods.
