There is Google's 4-1-1 service, there are also apps you can put on the phone such as the White Pages.com app.. These basically turn you into 4-1-1 operator once you get good enough at using them.
Google itself can often provide the info on a basic search.. For example:
Google: Restaurants 48423,, Will get you listings for all restaurants in Davison, MI (zip code 48423)
Or Google: Archie's Restaurant, Davison, Mi. (or 48423) will get you one specific restaurant, followed by many others.
Google me.. Won't get you a phone number, but then neither will White pages or 4-1-1 cause ... Well.. I opted out.
