Answer

This is because you have declared the code outside the controller div. It must be like this :

<div class="container">
 <div class="row row-content" ng-controller="dishDetailController as dishCtrl">
  <div class="col-xs-12">
    <p>Put the dish details here</p>

    <div class="media">

      <div class="media-left media-middle">
        <a href="#">
          <img class="media-object img-thumbnail" ng-src={{dishCtrl.dish.image}}>
        </a>

      </div>
      <div class="media-body">

        <h2 class="media-heading">{{dishCtrl.dish.name}}S
                    <span class="label label-danger">{{dishCtrl.dish.label}}</span>
                    <span class="badge">{{dishCtrl.dish.price | currency}}</span>
                    </h2>
        <p>{{dishCtrl.dish.description}}</p>
      </div>
    </div>
  </div>
  <div class="col-xs-9 col-xs-offset-1">
  <blockquote ng-repeat="commenta in dishCtrl.dish.comments">
    <p>{{commenta.rating}}</p>
  </blockquote>

</div>
</div>

Here is the updated code

Hope it helps :)
