this is because a call to Response.Redirect will simply send a 302 Code to the Browser (page moved). The page body will not be rendered, the browser requests the next page (menu.aspx).

You could redirect the user via javascript to get your message box visible:

 Response.Write("<script langauge=\"javascript\">window.alert('Acceso no permitido')</script>");
 Response.Write("<script langauge=\"javascript\">document.location.replace('Menu.aspx')</script>");
