just add another for loop inside it creating another dimension for that row — Kevin

Just use good ol' for loop. First get the count, then create the necessary rows:

$count = count($menu_id); // get count
for($i = 0; $i < $count; $i++) {
    $_SESSION['items_' . $restaurant_id]['menu_' . $i] = array(
        'user_order_id' => $last_order['user_order_id'],
        'menu_id'       => $menu_id[$i],
        'qty'           => $qty[$i],
    );
}
