Функции меню.
Taxonomy
Само меню - это таксономия (термин) типа nav_menu:
При этом в метаполях термина пусто:

Для получения такого объекта термина есть функция wp_get_nav_menu_object().
print_r( wp_get_nav_menu_object( 37 ) ); /* WP_Term Object ( [term_id] => 37 [name] => Футер [slug] => futer [term_group] => 0 [term_taxonomy_id] => 37 [taxonomy] => nav_menu [description] => [parent] => 0 [count] => 1 [filter] => raw ) */
