layout difficulty in MVC3 - asp.net-mvc-3

Question

I am having a login page. In the login Page I don`t have any menu and based upon the user login a menu appear on the Home page.
My problem is how not to display the menu only in my login page?
I am having a page MenuControlPartial.cshtml as follows for the menu:
<li>Admin
<ul>
<li>TimeKeeper</li>
<li>AAA</li>
<li>BBB</li>
<li>CCC</li>
</ul>
</li>
<li>Settings
<ul>
<li>VV</li>
<li>XX</li>
</ul>
</li>
</ul>
My _layout.cshtml is as as follows:
<div id="page">
<div id="header">
<div id="title">
<br />
</div>
#if (Request.IsAuthenticated)
{
<div id="loginInfo">
#Html.Partial("_LogOnPartial")
</div>
<div class="clear">
</div>
<div id="menucontainer">
#Html.Partial("MenuControlPartial")
</div>
<div class="clear"></div>
}
</div>
<div id="content">
#RenderBody()
</div>
</div>
}
</body>

You could test the current controller and action
#if (!(Html.ViewContext.RouteData.GetRequiredString("controller") == "Login" && Html.ViewContext.RouteData.GetRequiredString("action") == "Index")) {
<div id="menucontainer">
#Html.Partial("MenuControlPartial")
</div>
}
And to avoid this ugliness write a helper:
public static bool ShouldDisplayMenu(this HtmlHelper htmlHelper)
{
var routeData = htmlHelper.ViewContext.RouteData;
var controller = routeData.GetRequiredString("controller");
var action = routeData.GetRequiredString("action");
return !(controller == "Login" && action == "Index");
}
and then:
#if (Html.ShouldDisplayMenu()) {
<div id="menucontainer">
#Html.Partial("MenuControlPartial")
</div>
}
