According to Seattle Times, Starbucks fields thousands of calls each year from customers phoning from the road to find the nearest Starbucks store.
Customers with cellphones and mobile devices can now save themselves the call. Mobile users can send a text message with the area’s zip code to MYSBUX (697289), and a list of nearby Starbucks stores will pop back.
I just tested it and it works. Now, if someone comes up with the same system for indie coffee shops, espresso addicts will be hooked up.
