A random afternoon at L's Caffe: The sounds of Spanish chatter and small children float around the room. The bilingual newspaper El Tecolote is scattered among the tables, and a sign on the front window declares that the Mission District's culture is "not for sale." Now walk directly across 24th Street to Sugarlump. The windows are clear of signs. The reading material here is The Wall Street Journal, The New York Times, or the San Francisco Chronicle. Of seven customers in the store, six are hunched over laptops. Both places offer a good cup of coffee at a fair price. But they serve two different cities.
