Unusual Japanese waiter

I promise this is not a comment on the restaurant industry. It's just a cute video of an unusual waiter in a restaurant in Japan. The reason the story caught my eye is that the restaurant is located in Utsunomiya (in east central Japan), which is where my son spent a summer as the leader of a group of YMCA campers. I wonder if he ever went to this restaurant....

(If you watch closely, you'll notice that the waiter snacks on edamame during his break.)
