How can I get a city name given a latitude & longitude

I already got the latitude and longitude of my location using this http://docs.unity3d.com/ScriptReference/LocationService.Start.html tutorial, however; I need to convert the latitude and longitude into the city name. I don't need to pinpoint my location on a map, I just need to get the city name. Any suggetions on how I can do it? Also if it will help, I'm using C# in my game. I've pretty much read all about Google Maps API but I still am far from understanding it. Any recommendations would be much appreciated.
