I have an array, I need to return a restaurant's name, but I only know the value of its food attribute (not it's index number).

For example, how could I return KFC if I only knew chicken?

restaurants = 

  [

    {restaurant : { name : McDonald's, food : burger }},

    {restaurant : { name : KFC,        food : chicken }},

    {restaurant : { name : Pizza Hut,  food : pizza }}

  ];
