A former swimming pool attached to one of Katowice's closed coal mines, this lovely brick building has been refitted to house the city's best sushi house and Japanese restaurant. With the added advantage of being at the Silesia City Centre, yet sovereign over its own independent space and atmosphere (they even have their own separate parking next door), Hana Sushi boasts a rich menu rife with Japanese delicacies and hot dishes for those still suspicious of the sushi fad. If you don't feel like making your way to Silesia's biggest shopping mall.
