We've just returned from Hokkaido and on our last night in Sapporo, we ended up in "The Nikka Bar". https://www.tripadvisor.com/Restaura..._Hokkaido.html
In a wonderful atmosphere and they offered basically all Nikka products.
I was wondering if this is a chain and tried to find out whether there are other Nikka Bars, e.g. in Fukuoka, Kobe or Osaka. Unfortunately, an (English) google search did not render any (conclusive) results.
Does anybody know these bars, is it a chain and is there a website where we could locate outlets?

Thank you!
