However, after the load is complete I see the loaded and styled content which is fine:
How do I prevent the flash of AngularJS code on my page ? Is this related to FOUC ?
Here is the HTML code:
<!doctype html>
<html class="no-js" lang="en" ng-app="MainApp">

<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Foundation | Welcome</title>
<link rel="stylesheet" href="css/foundation.css" />
<script src="js/vendor/modernizr.js"></script>
<style>
.row.full-width {
width: 100%;
margin-left: auto;
margin-right: auto;
max-width: initial;

Please see my answer as well for an alternative solution in addition to the accepted one.
Answer
ng-cloak will help to some extent, but you can fully prevent it using ng-bind directive instead of using {{ }}.
e.g.
<td ng-bind="val.monthly"> </td>
not
<td>{{val.monthly}}</td>
