It used to be difficult to eat at Ootoya because there is only 1 outlet in Singapore, and the queue is never ending. Then, they opened another outlet at Suntec. Within a few months, the 3rd branch at Clementi Mall started operation.
Ootoya serves pretty good quality Japanese food, and you can get a meal within S$20. Service varies branch to branch, and also depending on the crowd size. I was at their Clementi Mall outlet on a weekday afternoon, and their customers here are mostly families and Japanese housewives who have just finished their shopping at Holland Village.
Ootoya serves free iced water. In fact, I notice that most Japanese restaurants here will offer free tap water when diners are seated without even asking.
Had the Oyakojyu Set (S$15.50) - Grilled chicken with egg on rice. The set came with appetizer (a chicken + vegetable stew), salad, miso soup and roasted seaweed.
Portion was big and the chicken had this aromatic BBQ taste to it. Would recommend this dish if this is your first time here, and you want to avoid fried food (which Ootoya is also famous for).
