Google has enhanced their Places API. It now provide access to expanded reviews content.
The company said:
Starting today, the Google Places API will feature Place Summaries, reliable reviews about points of interest. This allows your application to embed useful review information. For example, car manufacturers can use the API to provide drivers with detailed reviews of local establishments directly in their in-car system.
The API already shows content from Zagat a very popular restaurant review platform that was recently acquired by Google.
Google faces intense competition from services like Yelp, Foursquare and Facebook in this segment of the market.
