2. Offer and promotion activities:

- Offer first-time consumption discount, buy-in discount or special dishes at a specific time to attract customers to try them out and urge them to visit again.

- launch limited-time promotional activities, such as lunch discounts and dinner packages, to attract working people or regular customers.

- Take advantage of festivals or local celebrations to carry out related promotion activities to attract customers to come to dinner.

3. Word-of-mouth marketing and customer interaction:
