You may drive right by this restaurant and never think to go in, it's store front is very nondescript and the parking lot is quite small and near a busy street. I recommend you overlook all of that and grab some food from here.
My boss and coworker took me here for my birthday lunch (at my request). The waitress brought us over some sort of chicken "bites" compliments of the house which were very tasty as we waited for our meals. They both had the sushi & sashimi combo ($15) which was very fresh and came with purple rice, miso soup and salad. I had the Bulgogi, Tempura and Sushi Bento box ($15). The portions were very generous and everything was really very good. I loved the Bulgogi especially, I had it "spicy" which suited me perfectly.
The interior of this restaurant looks like an old Irish pub with white washed walls and dark beamed ceilings, however the dim lighting and added decor touches made it a bit more authentic feeling, nice comfortable environment. It was a bit warm for my liking though (the only reason I didn't rate it 5 stars) It was also quite busy for a Tuesday at lunchtime, pretty much full. I did feel the waitresses rushed us a bit, never asked if we wanted any dessert, just brought the bill when she saw were were done.
I do recommend Sushi-Ya Japan, it's great food at a great price.
