Just had dinner at Sachiko with my wife and daughter. The fish is pretty fresh ( we are not in Tokyo and the ocean is not visible in Tucson:)). That said, it is a good as it gets here. There are always a number of specials at very low prices. We had yellowtail toro which was wonderful, and a lobster roll that we loved. The tuna toro and white tuna (albacore) were also excellent.
The restaurant is a strip mall joint with a diner like interior. A small price to pay for first rate sushi and low prices.
