Loop through an array from JSON using Angular JS

I am trying to loop through an array from JSON and display the contents more like a side menu. I wrote something like

<ul ng-repeat="(key, value) in menuList.Menu">
  <li>{{key}}</li>
  <ul ng-repeat="(key, value) in value">
    <li> {{key}}</li>  //second key
    <ul ng-repeat="(key, value) in value">
      <li> {{key}}</li> 
      <ul ng-repeat="(key, value) in value">
        <li> {{key}} : {{value}}</li>  
      </ul>
    </ul>
  </ul>
</ul>

The problem is my second key has both object and array. How do I display the value of Object and loop/ng-repeat just through the array. I cannot modify it with this as it will display the entire content of the array.

 <li> {{key}} : {{value}}</li>  

A part of my JSON for better understanding is given below:

{
  "class": 99,
  "mode" : 0,
  "Menu": [{
      "MenuNum":  1,
      "MenuItems":  [{
          "ItemNum":  0,
          "ItemDesc": "Main Menu",
          "ActionCode": "-",
          "ActionInst": ""
        } , {
          "ItemNum":  1,
          "ItemDesc": "BBQ",
          "ActionCode": "M",
          "ActionInst": "0992"
        }, {
          "ItemNum":  2,
          "ItemDesc": "Beverages",
          "ActionCode": "M",
          "ActionInst": "0992"
        }]
        },{
      "MenuNum":  2,
      "MenuItems":  [{
          "ItemNum":  0,
          "ItemDesc": "Sub Menu",
          "ActionCode": "-",
          "ActionInst": ""
        }, {
          "ItemNum":  1,
          "ItemDesc": "BBQTYPE1",
          "ActionCode": "P",
          "ActionInst": "0996"
        }, {
          "ItemNum":  2,
          "ItemDesc": "BeveragesTYPE1",
          "ActionCode": "P",
          "ActionInst": "0998"
      }]
  }]
}

I want the sidebar more like
