1.800.GOO.G411 a/k/a 1.800.466.4411
(Dailing 8 more digits is certainly worth a buck fifty to me)
It's a free service that not only includes the telephone number but the address too. Unlike the other services, it also offers optional addresses. Let's say you want a local Best Buy, but your not sure which town it is in. Just guess the town, and it gives up to 8 options. Also, it actually gives you the number and doesn't automatically connect you without the number. Want a record of the number, it will text message the details to you.
