I work just blocks from Kokiyo Teriyaki and seeing as I don't have a car, I tend to frequent the same few restaurants for lunch... this happens to be one of them. The service has always been pleasant and friendly. The food and the quantity are decent for the price. I have only had the vegetable yakisoba, but for an average lunch spot, it was pretty good. I don't eat there very often because the food is a little greasier than I would prefer and I can't seem to eat the whole plate (and don't really like leftovers). The atmosphere is lacking, bad lighting and a TV playing sappy daytime movies or sports is an unwanted distraction on my measly half hour break. But... it's a quick, filling meal... I just wouldn't eat here if I wasn't on my lunch break.
Pros: Friendly service, Quick
Cons: Bland atmosphere, Annoying TV
