How to write the introduction of snack bar attractive?

1, first of all, you can write "Welcome to our store, our store is newly opened, and we operate with integrity, only earning credibility but not making money, thank you".

2. Secondly, the text introduces the products of the store: "All the goods in this store are authentic, with rich categories, favorable prices, ten penalties for one fake, and credit guarantee".

Finally, I want to express my gratitude to "Welcome customers to buy with confidence and serve wholeheartedly".
