If you have not heard about GOOG-411 you are missing out.  This is a free service you can use from your cell phone or home phone in the US to find out what a business phone number is.  It beats paying one or two dollars for the traditional services offered by the phone companies.  When you call up you say where you are and what you are looking for.  GOOG-411 will then connect you with the business.  You can also opt to have a text message sent to you or to have a map sent to you with the location.  Once you get used to using it you will wonder how you ever lived without it!
