They are great "foodies" and loved trying out all sorts of Japanese food.
I remember they mentioned that one thing they thought was a bit annoying was the slurping sound the Japanese made when eating.
When I celebrated my birthday at a Japanese restaurant in March this year, I saw this explanation on the menu, and that slurping sound has a name.
I think the slurping sound would highly annoy me too... What about you?
