For me, Ootoya is one of the good authentic Japanese restaurant. A little bit pricey but you will get what you pay in the end. We tried several different menus, the eel was good, oyako don (chicken and egg served on top of rice) was consistent as always, and the egg and veggie soup was surprisingly good. I tried natto and sashimi bowl; first-timer natto, taste was unique (:D) but nevertheless the sashimi bowl was good.
Location of tasting: Lotte Shopping Avenue, Jalan Professor Doktor Satrio No.3-5, RT.18/RW.4, Karet Kuningan, RT.18/RW.4, Karet Kuningan, Kota Jakarta Selatan, Daerah Khusus Ibukota Jakarta 12940.
