The kitchen style of Chez Hans is International with Irish influences.
In the time the restaurant was awarded the Michelin star, the head chef was Hans Peter Matthiae. In 1998 he handed the ladle over to his son Jason Matthiae.
The restaurant is housed in the former Synod Hall of the (Protestant) Diocese of Cashel and Waterford and was used as such until 1950. The diocese sold the building that year to a businessman who sold it to Hans Matthiae in 1968. After an extensive renovation the building started a new life as a restaurant.
