I believe line 31 is the problem
<li class="media" ng-model="dishc in dishCtrl.dish" >
<li class="media" ng-repeat="dishc in dishCtrl.dish" >

Also i only have 1 dish item as you can see below in the code.
here is what the final product should look like.

Ok - that is helpful - you will need to help us here we don't know what you are aiming at.
What was your intention here?
There are a number of things that you need to fix with the code
1. The ng-model - you don't need this on the <li> I see what you were trying to do but that is not the correct way - see below for an explanation
2. Your comments are outside of the controller block - which means you won't be able to access the comments - you need to put that inside the controller block.
Let's break your code down.
You have elected to use the controller as approach instead of scope - which is good but here is how it works.
In your controller you have the structure called dish. You are making this a controller property by this line
(A)
In your html you have
Going back to the code snippet (A) your controller representation of your data is dish - therefore to output the values of your model you need to reference them as
So for the image this would be

Thank you for being an excellent resource. I was using ng-model just because I thought it was the right directive.
Active today
ng-model is for binding a view element to your model - i.e. elements that have a value.
To access the view for output or expressions you either use the controllerAs prefix to dereference the property you want in your controller - or if you are not using controller as (scope) then you can refer to the property directly.
Glad to be of help and you are most welcome.
