Google added a "Businesses" layer to Google Earth for iPhone application, as well as to the "Geographic Web" folder in desktop version. Which displays automatically, when you start the application, and helps in finding businesses like restaurants, bars, banks, gas stations, and grocery stores all just a touch away. Clicking on the icons, you'll get additional information like the telephone number, reviews, hours, and much more. And don't forget, as you zoom in further, more businesses become visible.
