This is how I fixed this kind of thing:

Model:
class Menu extends AppModel {
        var $name = 'Menu';

        // model validation
        var $validate = array(
                'naam'        => VALID_NOT_EMPTY,                // backwards compatible
        );

        function maakMenu($belongs_id = '0') {
                $menu_voor_view = array();
                $menuitems = $this->findAll("belongs_to = '$belongs_id'", '',
'Menu.zwaarte ASC');
                foreach($menuitems as $item) {
                        $item = $item['Menu'];
                        if ($item['url'] == '') {
                                $submenu = $this->maakMenu($item['id']);
                                $menu_voor_view[$item['naam']] = $submenu;
                        } else if ($item['sub'] == '1') {
                                $submenu = $this->maakMenu($item['id']);
                                $menu_voor_view[$item['naam']] = $item['url'];
                                $menu_voor_view[$item['naam'].'.sub'] = $submenu;
                        } else {
                                $menu_voor_view[$item['naam']] = $item['url'];
                        }
                }
                return $menu_voor_view;
        }
}

$menu_voor_view = array to return
naam = link name
submenu = int to indicate if this menu has submenu's or not, so as to
allow a topcategory to have a url and subitems (it normally assumes
that if no url is there, it must have a submenu)
belongs_to = id of topcategory
zwaarte = shows the location of a specific menu in the list of all

Controller:
class MenuController extends AppController {
        var $name = 'Menu';

        function maakMenu($belongs_to = '0') {
                if (isset($this->params['requested'])) {
                        $menu = $this->Menu->maakMenu($belongs_to);
                        return $menu;
                } else {
                        $this->redirect('/');
                }
        }
}

this just returns the menu array made in the model (and as it is
recursive there, it returns a complete menu array)

To include a menu on a view, I created an element and that is
rendered:
$menu = $this->requestAction('menu/maakMenu');

function printSubMenu($submenu, $html, $eerste) {
        print '<ul';
        if ($eerste) {
                print ' id="nav"';
        }
        print '>';

        foreach($submenu as $naam => $url) {
                // checking for submenu
                if (!ereg('.*\.sub', $naam)) {
                        print '<li>';
                        if (is_array($url)) {
                                echo $html->link($naam, '#');
                                printSubMenu($url, $html, false);
                        } else if (isset($submenu[$naam.'.sub'])) {
                                echo $html->link($naam, '#');
                                printSubMenu($submenu[$naam.'.sub'], $html, false);
                        } else {
                                echo $html->link($naam, $url);
                        }
                        print '</li>';
                }
        }
}

// $html is needed to use the $html helper functions!
printSubMenu($menu, $html, true);
