Usability 
Yahoo Local search is a little strange. It's as if it were based on the Business White Pages and returns listings that contain the search string in their name. Thus a search for "restaurants" will only find those establishments with "restaurant(s)" in their names. This means that it's really only practical to search by an establishment's name. Once you have found what you are looking for, Yahoo displays your destination on an appropriately small (128 x 128px) map and provides driving directions to it.
