We did a team lunch here today and I loved the place sans the service. And the service wasn't courteous and friendly. It was just that there was only one a lady waiting on everyone. Great food - I had the bento but tasted some of my colleagues nigiri and it was fantastic.
I also liked the little booths they have with curtains - feels very intimate. It is not chic but a great value for lunch.
Heads up - it's tiny and very few tables.
