Overdose

America is infatuated with coffee. So much so that a recent National Geographic Magazine dedicated the cover and a large portion of the magazine to it (well, more specifically, to caffeine). Did you know that if you lived at 25th and Broadway in New York City, you would have your choice of 172 Starbucks within a five mile radius of your apartment? See for yourself.
Apparently, NYC isn’t particularly Starbucks dense (from this article in 2003):

Currently, Starbucks operates 161 stores in New York City or one store for every 57,852 people. Glass estimates, however, that Starbucks will not approach saturating the city’s market until it has opened at least 466 stores and could manage to open as many as 515 stores.
In fact, compared with other United States cities, New York’s Starbucks are few and far between. Seattle – the company’s home – boasts the highest concentration of stores, with one for every 13,340 people. San Francisco houses the second highest density.
On the other end of the spectrum, Glass found other metropolises in which Starbucks was all but non-existent. Philadelphia, for example, has only 41 stores.

Amazing.
