As well as HK they also have branches in London.
The UK Kanada-ya website has menu and prices but the HK one doesn't have prices but it seems a HK thing to not put prices.
Basically it is a competition to finish your noodles in the fastest time and the one who does gets tickets to Japan and back.
Other prizes include watches.
I went for the Original ramen.
The ramen was firm and the broth had a strong fish taste which was strange but it was thick and viscous and not too oily.
It was not too salty and didn't have MSG which was good.
