Update: Much better experience on our 2nd visit. This time we bought more family members and ordered more food.
We ordered black ramen, seafood black ramen, 2 orders of tonkatsu ramen, bento box, korean ramen, and 2 orders of takoyaki. On top of our huge order we got a bowl of curry don for free(that day they had an offer: If you spend $50 or more you get the curry don for free)!This time all of our dishes were excellent(lacking in presentation a lil bit), I especially loved their curry don and black ramen. They even gave use free mini mango pudding shots.
Service was great as well except for at the start we waited around 15 minutes to get our drinks. Even though the restaurant was busy, since we came at lunch time, our orders came right away.
For the quantity and quality of food we got, and for the price, definitely would recommend Wami Ootoya to friends and family.
