Atmosphere: The place was dirty, the floor was extremely sticky, there was a mysterious brown liquid on the wall. There is no room. I hit the wall with my elbow trying to eat. It is literally a hallway with tables. The tables were clean and so were the chairs.
Food: The food was merely mediocre. I got the veggie tempura roll but it wasn't particularly good. They gave me just enough wasabi for 4 pieces. And there was a creamy unidentifiable sauce in the soy sauce. My meat eating friend got pork dumplings and said the texture was off and it was bland. Their food was the best part. But nothing compared to the other sushi places in concord.
Service: Was pretty much not great. We had to get up and get our own box for leftovers. They clearly favored a large group that made a reservation. They put lemon in your drink without asking.
