Using this service, you can:

search for a local business by name or category.You can say “Giovanni’s Pizzeria” or just “pizza”.
get connected to the business, free of charge.
get the details by SMS if you are using a mobile phone. Just say “text message”.

And it’s free. Google doesnt charge you a thing for the call or for connecting you to the business. Regular phone charges may apply, based on your telephone service provider.

Found this new service in Google labs and thought it was worth a blog post.
