Meet the Sushi Master
Noritada Saito

Noritada Saito, the Czech Republic’s only true Sushi Master, was born in the Japanese city of Nagoya.

He inherited his talent in the culinary art from all of the men on his mother’s side and he nurtured it to perfection over his 30 years of experience.

Being a Sushi Master is not only his lifestyle but his life philosophy.

People in Koishi

The concept and the physical appearance of KOISHI originated almost two years. But Janko Martinkovič began playing with an idea to open his own business decades ago. His dream dot clearer outlines in 2006 when he found an ideal place for his plan in emerging gourmet district on Údolní Street.

With all due respect to the local sushi, I recommend everyone to try the second dimension of the menu. Unreal! Excellent harmony of pure tastes, Kambala with beef cheek, Zander with blood sausage, Jerusalem artichoke soup, coconut curry soup, unbelievable desserts – gastronomic top.
