The promotion of "small portions" and "half portions" may increase the time, manpower and material costs, but it will also bring many positive effects, especially in today's economic environment, which can better meet the needs of consumers, increase sales, and improve customer loyalty and return rate.

First of all, the promotion of "small portion" and "half portion" programs requires an appropriate increase in human and material costs. Small portions and half portions need more production time and labor costs than ordinary portions, and at the same time, it is necessary to control the consumption and cost of ingredients more accurately. However, this cost increase can be made up by increasing the unit price and sales volume of customers, because consumers are more willing to buy small or half dishes.

Secondly, the promotion of "small portions" and "half portions" will help to increase sales and customer loyalty. With people's concern for healthy eating and the demand for saving consumption, promoting small portions and half portions of dishes can better meet customers' needs, reduce waste, increase sales and customers' return rate. In addition, providing more choices will also help attract new consumers and improve customer satisfaction and loyalty.

finally, the promotion of the "small portion" and "half portion" schemes will help to improve the brand image and competitiveness of restaurants. In the catering market, providing more choices and better service quality can establish a more positive brand image for restaurants and attract more consumers. In addition, this scheme also helps to increase the competitiveness of restaurants, distinguish them from competitors and increase market share.
