It doesn't work properly when you try to access it with HTTPS. My guess is the CSS is not loading properly, page comes out all wonky.
If you google "Ginza Club", you will get the shop "card" where you have the map and buttons to get to the shop website, etc. The website button on this card works, it goes to the non-HTTPS site.
But if you clicked on the top search results, not the card, you will go to the HTTPS site instead.
