Pass the 'foo' and 'bar' category $id values as an array to the
`category__in` parameter:
$args = array( 'category__in' => array( 1, 2 ) );
$custom_query = new WP_Query( $args );
p.s. avoid query_posts() here. Use a new instance of WP_Query() if you're
creating a secondary loop, or filter the main $query via pre_get_posts, if
you're modifying the main query.
