Defining Japanese Fast food.
It has been a while since I have found a place that does authentic Japanese fast food. After spending several months in Japan, I have not found any place that is close to the real deal, until Tombo. It's not fancy and you are not waited on by the staff. But the food is fresh cooked when you order it and you get lots of it. My favorite is the Chicken Yakisoba (fried noodles). It's not over done or oily and a good selection of veggies. A very good choice for lunch.
