We were a group of 12 people, and we ordered different dishes. The service was quick for the group that ordered separate dishes, but another group asked for sushi "boats" and they took almost an hour to serve them, when the others had finished eating. The manager's response was that orders were made as they were received, but this is not true, because the "boats" were ordered first. She was arguing with us trying to remedy the mistake, but it was getting worse and worse. Anyway, the attention was terrible. They lost 12 clients.
