Not too long ago, sushi is still considered to be a specialty that can be enjoyed only in traditional Japanese restaurants or specialty shops and demand for sushi is not common among general population. The length preparation period and its expensive pricing has been a barrier towards allowing more people to taste this wonderful dish.
Kaiten Sushi (or its many other names- sushi conveyor, revolving sushi, sushi train to name a few) has helped bought sushi to the masses locally and probably helped sushi earned the international recognition which it now enjoys.
