It is a very friendly and nice atmosphere, food was excellent and choice of wine, sake is very good.
I can certainly recommend to people try a something typical Japanese such as Sashimi Moriawase and also Teppanyaki.
Tatsuso serves good sushi at City prices. It is considered to be one of the premium venues to entertain in the Square Mile. Food is first class - teppanyaki tables at entrance level, Sushi Bar and A La Carte downstairs. Service is efficient by staff in traditional Japanese costume. Private rooms are highly sought after so book well in advance.
