menu item problem

I have menu code that results in two main tabs and two subtabs under the default local task. Where is menu link ? I expected http://site/milkshake

I don't have any items of milkshake in my menu.

function milkshake_menu($may_cache) {
	$items = array();

	if (!$may_cache) {
	$items[] = array(
	'path' => 'milkshake',
	'title' => t('Milkshake flavors'),
	'callback' => 'milkshake_overview',
	'type' => MENU_CALLBACK
	);

	$items[] = array(
	'path' => 'milkshake/list',
	'title' => t('List flavors'),
	'type' => MENU_DEFAULT_LOCAL_TASK,
	'access' => user_access('list flavors'),
	'weight' => 0
	);

	$items[] = array(
	'path' => 'milkshake/add',
	'title' => t('Add flavor'),
	'callback' => 'milkshake_add',
	'type' => MENU_LOCAL_TASK,
	'access' => user_access('add flavor'),
	'weight' => 1
	);

	$items[] = array(
	'path' => 'milkshake/list/fruity',
	'title' => t('Fruity flavors'),
	'callback' => 'milkshake_list',
	'type' => MENU_LOCAL_TASK,
	'access' => user_access('list flavors'),
	);

	$items[] = array(
	'path' => 'milkshake/list/candy',
	'title' => t('Candy flavors'),
	'callback' => 'milkshake_list',
	'type' => MENU_LOCAL_TASK,
	'access' => user_access('list flavors'),
	);
}
return $items;
}

Sorry for this simple question.
