Google has an experimental service to make local-business search accessible over the phone, and it is free! Google doesn’t charge for the call or connecting you to the business, BUT regular phone charges may apply (based on your telephone service provider)

"To try this service, just dial 1-800-GOOG-411 (1-800-466-4411) from any phone.
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’re using a mobile phone.
Just say "text message"."

Note: Google Voice Local Search is still in its experimental stage. It may not be available at all times and may not work for all users. It’s currently only available in English, in the US, for US business listings.
