Conveyor belt sushi restaurants are classic xxx movies - watch full movies for freenothing revolutionary in Japan. These kaitenzushi restaurants are ubiquitous in that country. However, when your food floats to you on water, the dinner theater aspect gets even more fun.

Donguri restaurant in Numazu City, Japan, serves mainly parfaits, sundaes and other desserts in wooden tubs that are floated to diners down a water-filled counter.

RocketNews24says this practice honors Japanese traditions, "There’s the summer custom of catching 'Nagashi Somen' or 'Flowing Noodles' with chopsticks from water-filled bamboo poles, and imperial courtiers once enjoyed writing poetry while sipping bowls of sake that flowed down streams as part of the 'Kyokusui-no-utage' or 'Meandering Stream Banquet Party.

After ordering at a self service machine (ordering via machine instead of from a human server is also popular in Japan), the diner clips the order ticket to a clipboard in a wooden tub then sends it on a watery voyage. When the tub with the order is ready, a white marker with the name of a Japanese city (each seat has a marker) lights up and you know the food-boat headed downstream is for you.

People are enchanted by the restaurant and it's easy to see why.

沼津駅南口の仲見世商店街の珍スポット「喫茶どんぐり」。回転寿司のようなカウンターの目の前に川が流れていて、食券を桶に入れて流すと出来上がった料理がどんぶらこ〜と流れてくる。フルーツパフェ(680円)。味は普通に美味しい。 pic.twitter.com/svt8K6FXXM

Eating and travel go hand in hand. It's just not often the food that does the traveling.
