Try this:

    $select = Zend_Db_Table::getDefaultAdapter()->select();
    $select->from(
        array('inventory' => 'k'),
        array(
            'ID'    => 'k.id',
            'NAME'  => 'k.name',
            'PRICE' => 'k.ppu_sell',
            'TYPE'  => 'k.type'));

    $selectClone = clone $select;

    $select->reset()->from(
        array('menu' => 'm'),
        array(
            'ID'    => 'm.id',
            'NAME'  => 'm.name',
            'PRICE' => 'm.price',
            'TYPE'  => new Zend_Db_Expr("'menu'")));

    $select = Zend_Db_Table::getDefaultAdapter()->select()->union(array(
        $selectClone, $select
    ));
