Android : Google maps api V2 type of food in a restaurant place

I'm getting a list of nearby restaurant within a range, no problem for that. What I'm trying to do is to know what type of food is served at each restaurant (pizza, chinese, pasta ...). When I do my nearby search with the keyword parameter set to chinese for exemple, that return me the chinese restaurants. But when I search in the json I don't find any reference to that (even if I search with a place detail request).

I assume this information must be somewhere since the keyword search works, but where ?

This is an example of what i get from json :

{
     "geometry" : {
        "location" : {
           "lat" : 47.284473,
           "lng" : 5.010973
        }
     },
     "icon" : "http://maps.gstatic.com/mapfiles/place_api/icons/restaurant-71.png",
     "id" : "26477da7bf70a3e1c763f548b3b4417fa267a927",
     "name" : "KFC",
     "opening_hours" : {
        "open_now" : false
     },
     "place_id" : "ChIJ0SqY2l2c8kcRhhlr_VR7CC8",
     "price_level" : 1,
     "rating" : 3.4,
     "reference" : "CnRkAAAAfAsvvcQ1TiJseFIo8WWAtrWvePZvoIU94n1FJ4AaX58gA6lV1Zmv0wISP1s_rAXrd5xEZPRiYUSo4Y5pubvhmSWWeNv9X33fFZrrM9yVPbH3n1kDHrnDGl5aUaajAbDBjOZL9MQtNo3AWHtbTK7wMxIQxMpxujaVv5fZDi2UKQtF2xoUzB2cJR0TEWT6JqL7-Am-uOL4cyk",
     "scope" : "GOOGLE",
     "types" : [ "restaurant", "food", "establishment" ],
     "vicinity" : "163 Avenue Rolland Carraz, Chenôve"
  }

Thanks.
