Shi Ding is not Chaozhou dialect, but a common dining form in Japanese restaurants. There are usually three kinds, one of which is Shi Ding, which is usually used at noon, that is, during a meal. There must be rice, pickles, miso soup or clear soup in the order, and the others can be matched with the price. For example, eel ordering, sashimi ordering and so on.
The other two are "Dangdang" (lunch box) and "conference cooking" (seasonal set meal)
