ACF: Querying relationship fields with Author

The users doesn’t have permalinks nor titles. They have author links and display names. Changed the code:

            <?php while ( have_posts() ) : the_post(); ?>

                        <h2>Resturants</h2>
                        <?php 

                        $resturants = get_users(array( // Changed from get_posts
                            'fields' => 'all_with_meta', // All with meta to get also display_name
                            'meta_query' => array(
                                array(
                                    'key' => 'resturant', // name of custom field
                                    'value' => '"' . get_the_ID() . '"',
                                    'compare' => 'LIKE'
                                )
                            )
                        ));

                        ?>
                        <?php if( $resturants ): ?>
                            <ul>
                            <?php foreach( $resturants as $resturant ): ?>
                                <li>
                                    <a href="https://wordpress.stackexchange.com/questions/188014/<?php echo get_author_posts_url( $resturant->ID ); ?>"><?php echo $resturant->display_name; ?></a>
                                </li>
                            <?php endforeach; ?>
                            </ul>
                        <?php endif; ?>
            <?php endwhile; ?>
