我的查询是：
$restaurantList = $this->Restaurants->find('all', [

'contain' => [
'DeliveryLocations' => [
'conditions' => $areaLocationConditions,
],
'RestaurantMenus' => [
'conditions' => [

简单解决方案
通过实现CounterCache https://book.cakephp.org/3.0/en/orm/behaviors/counter-cache.html并按缓存结果排序 .
更复杂：
通过使用Case语句
https://book.cakephp.org/3.0/en/orm/query-builder.html#case-statements
如果餐厅有菜单，则选择'has_menus'，然后选择其他0
按此结果排序
