Which structure of JSON should I use?

I am making angularjs application and wonder what type of json structure should I use. I don't know how many types of food (I mean Drink, Food keys) will be finaly. What type of structure will suit best for app development. Here is my two propositions:

Separate products in menu categories:

var restaurants =
    [
        {
            name: 'Restaurant1',
            id: 0,
            menu: {
                Drink: [
                    {
                        name: 'Beer1',
                        price: 5,
                     },
                    {
                        name: 'Beer2',
                        price: 5,
                    }
                ],
                Food: [
                    {
                        name: 'Pizza1',
                        price: 5,
                    },
                    {
                        name: 'Pizza2',
                        price: 5,
                    }
                ]
         },
         {
            name: 'Restaurant2',
            id: 1,
            menu: {
                Drink: [
                    {
                        name: 'Beer1',
                        price: 5,
                     },
                    {
                        name: 'Beer2',
                        price: 5,
                    }
                ],
                Food: [
                    {
                        name: 'Pizza1',
                        price: 5,
                    },
                    {
                        name: 'Pizza2',
                        price: 5,
                    }
                ]
         }
 ]

OR All products together + add type value for every product

var restaurants =
[
    {
        name: 'Restaurant1',
        id: 0,
        products: [
                {
                    name: 'Beer1',
                    price: 5,
                    type: 'drink'
                 },
                {
                    name: 'Beer2',
                    price: 5,
                    type: 'drink'
                },
                {
                    name: 'Pizza1',
                    price: 5,
                    type: 'food'
                },
                {
                    name: 'Pizza2',
                    price: 5,
                    type: 'food'
                }
                 ]
     },
     {
        name: 'Restaurant2',
        id: 1,
        products: [
                {
                    name: 'Beer1',
                    price: 5,
                    type: 'drink'
                 },
                {
                    name: 'Beer2',
                    price: 5,
                    type: 'drink'
                },
                {
                    name: 'Pizza1',
                    price: 5,
                    type: 'food'
                },
                {
                    name: 'Pizza2',
                    price: 5,
                    type: 'food'
                }
               ]
     }
