Generally, each dish has a fixed amount, which is called an example card. If some guests have a large number and don't want to order 2 copies, you can do a medium card (the proportion of cards is more and the price is more expensive), and if there are many people, you can also do a large card, which is actually large, medium and small. However, a sample card is usually enough.

For example, there are rules. In a restaurant, there is a fixed amount or method of ingredients used in each dish. If there are no special requirements when guests order, the chef will process the dishes according to the specified quantity and method, so it is called a sample card. However, this is what insiders say, and it is generally not used as a guest language when serving food in the hall.
"Example" here refers to a dish or a soup. "Example" is also a quantifier, but the usage of this "example" is not standardized, and it should still be "Tao". The exact amount of food or soup varies from restaurant to restaurant. Some use standard soup pots, and some use small utensils. And there is a big difference between north and south. Therefore, we can't use "examples" to express the amount of vegetables or soup.
