I just finished downloading the application to my friends? phone.

Here what it does in a nut shell:
 
?Combining directions, maps, and satellite imagery, Google Local for mobile is a free download that lets you find local hangouts and businesses across town or across the country ? right from your phone.

Detailed directions: Whether you plan to walk or drive, your route is displayed on the map itself, together with step-by-step directions.
 
Integrated search results: Local business locations and contact information appear all in one place, integrated on your map.
 
Easily movable maps: Interactive, draggable maps let you zoom in or out, and move in all directions so you can orient yourself visually.
 
Satellite imagery: Get a bird's eye view of your desired location.?

Google recommends adding an unlimited data plan to your current account to avoid unexpected charges. Makes me wish I didn't have Verizon :(
