Although we have lived in the area for several decades, this was our first visit to Ota-Ya. When we arrived at its off-the-beaten-track location last Saturday evening, we discovered that it was smaller than we expected and quite busy. However, we did manage to get the last available table. The manager was friendly and engaging, and she promptly made sure we were attended to.
Apparently from other reviews, many locals come for the sushi; however, we ordered a tempura (Chicken & Vegetable) and two udon (Nabeyaki and Yaki) entrees. While we were waiting for our meals, the manager came over and talk with us for several minutes, despite the restaurant being quite busy. Soup and salad were tasty, though I thought they could have been a bit less salty. The main courses soon arrived, hot and very tasty. Portions were larger than at most Asian restaurants in the region at which we have eaten. For example, the tempura entree included six large pieces of chicken and six vegetables.though I did not partake of the udons, both of my companions were very pleased with their choices.
Though quite full after the main meal, the manager convinced us to share what was a a large serving of tempura green tea ice cream. We liked the ice cream itself but In hindsight, given the size of our meal, I think we would have been happier with a scoop of plain green tea ice cream.
We plan on returning to Ota-Ya in the future. Both from reading other reviews and our own experience we will plan on going on nights when it is less busy or else make advanced reservations.
