Attract more customers: Double package is usually more cost-effective than single package, so it is easier to attract customers. Displaying the set meal for two on public comments can make customers more easily attracted by the discount and attraction of the set meal when browsing restaurant information, thus increasing the exposure and popularity of the restaurant. Enhance brand image: Merchants who offer double packages often give people a more warm and romantic impression, which helps to enhance brand image.

Enhance the customer's stickiness: By providing an attractive set meal for two, customers will have a better impression and experience of the restaurant, thus increasing the customer's stickiness and loyalty. These customers may become repeat customers of the restaurant and bring more benefits to the restaurant.
