Kurumiya in Hachimanyama
Looking to confirm the days and times for the takeout window, not the "Dining" branch in Keio Hachimanyama station. A coworker says that he thinks they are only open on weekdays.
Their home page (http://www.kurumi-ya.com/main.shtml) has no times for the takeout shop, only for the Dining branch. Various other reasonably-well-thought-out internet searches yield nothing.
