Use the Yelp grub finder search webapp to easily search for food and drinks using your iPhone. Once you find what you are looking for, you can easily give them a call, or plot them on the built in Google maps by clicking on the call or map links on the full listing of the business.

Update: Yelp Grub Finder now includes an auto complete drop down for locations when you do a search, bigger call and map buttons, 3 review snippets instead of 1, and the reviewers picture, name and links to their yelp profiles. Try with TestiPhone
