About us

KOISHI – restaurant focused on fish and sushi. The menu is composed of original and contemporary European cuisine closely linked to Asian elements.
The highest quality in seafood, saltwater fish and freshwater fish is essential to our chef’s preparation.

The accent of fresh ingredients forms the ideal conditions for sushi prepared by our Sushi Master – Noritada Saito.

This is not only the cornerstone of the philosophy by which we run our restaurant but it is the whole mosaic that adds to the further quality without which one could not fully grasp unless they visit us.

Meet the owner
Janko Martinkovič

born in Bratislava in 1966 to a Slovak father and a Moravian mother, a bon vivant – but with a strong social and community consideration, a restaurateur  – but an occasional fast food lover, a Doors Revival Band Brno singer – but a keen fan of The  Beatles, having grown up on their music, devoted to the Zbrojovka team – but an orthodox fan of Manchester United, a wine connoisseurs  – but six beers in the renown  Blahovka pub can only be beaten by the six beers in the renown Blahovka pub…

He strongly dislikes: coloured football boots … (those should be black and only black), having to borrow the hose pipe at the petrol stations – both with or without the deposit (- it is so undignified!!!); TV commercials for chilled chicken (those simply do not belong there!); pro-Sparta commentators of the football league matches (it is, to say it simply-heinous).

He likes eating oysters and making soups of all kinds. Thanks to his absolute taste recognition memory he was one of the first Brno residents to have received a certificate of the Association of Sommeliers of the Czech Republic in 2004 as one of the first among the Brno citizens.

Ever since it’s establishment the restaurant has been ranking at the top places in the Maurer’s Grand Restaurant  Selection.

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.
