I haven't tried this yet, but at $1.50 - $2.00 for 411 calls through your cell phone provider, it's definitely worth checking out. Try it out and let me know how you like it.
"Google Voice Local Search is Google’s experimental service to make local-business search accessible over the phone.
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".
And it's free. Google doesn’t 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.
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.
We’re fine-tuning the service to get better at recognizing your
requests. It’s currently only available in English, in the US, for US
business listings.
