Trouble Binding Data From XML in ASP.NET

I am trying to populate my model with data from an XML file, but have been unsuccessful so far. Setting a breakpoint at the variable Res shows a null value.

I also tried loading the XML file locally, but the outcome was the same.

I am using VS2013, MVC.

Controller:

public ActionResult Index()
    {   
        IQueryable<Restaurant> Res;

        XDocument xmlDoc = XDocument.Load
        ("http://ift.tt/12QHtvT");

        var model =
        from xml in xmlDoc.Descendants("EstablishmentDetail")
        select new Restaurant
        {
            FHRSID = (int)xml.Element("FHRSID"),
            BusinessName = (string)xml.Element("BusinessName"),
            RatingValue = (int)xml.Element("RatingValue"),
            HygieneScore = (int)xml.Element("Hygiene"),
        };

        Res = model.AsQueryable();

        return View(Res);
    }

Model:

[XmlRoot("EstablishmentDetails")]
public class Restaurant
{

        public int? RestaurantId { get; set; }

        [XmlElement("FHRSID")]
        public int FHRSID { get; set; }
        [XmlElement("BusinessName")]
        public string BusinessName { get; set; }
        [XmlElement("RatingValue")]
        public int? RatingValue { get; set; }
        [XmlElement("Hygiene")]
        public int? HygieneScore { get; set; }
 }

Sample from the XML file:

<FHRSEstablishment>
 <Header>
  <ExtractDate>2014-09-19</ExtractDate>
  <ItemCount>933</ItemCount>
  <ReturnCode>Success</ReturnCode>
 </Header>
 <EstablishmentCollection>
  <EstablishmentDetail>
   <FHRSID>129104</FHRSID>
   <LocalAuthorityBusinessID>5952</LocalAuthorityBusinessID>
   <BusinessName>5 Elm's Cafe</BusinessName>
   <RatingValue>3</RatingValue>
   <Scores>
    <Hygiene>10</Hygiene>
    <Structural>10</Structural>
    <ConfidenceInManagement>10</ConfidenceInManagement>
   </Scores>
  </EstablishmentDetail>
 </EstablishmentCollection>
</FHRSEstablishment>

I am quite new to web development in general, this is my first time working with XML files.
