Conditional Logic Based on Custom Taxonomy

@Milo was absolutely correct…the issue was that I wasn’t getting a string to compare. The solution actually came from here.

What this ultimately looked like in my scenario:

    <?php
        if(has_term('dining-1', 'page_category', $post->ID)){
          get_template_part('sidebar', 'dining-one');
        }
        elseif(has_term('dining-2', 'page_category', $post->ID)){
          //etc.
        }
    ?>
