Google is about to serve the restaurant guests
Google wants to serve information to users without them searching for something, but based on their browsing or location profile, “contextual discovery”. For example: If you’re in a restaurant, Google can, based on the location of your mobile, provide you automatically a message with a link to the menu, along with indications of what your friends like to eat. Coming in 2011.
