In the food city, there is a large flow of food and beverage, but there is also great competition. Therefore, the dishes must be distinctive and differentiated. The first is advertising. Make an advertising display board in front of your own store or the door where there is no market, and show your most distinctive dishes that can attract guests. The photos of the dishes should be appetizing, so that guests can see the appetizing dishes at the door without looking at your recipes. Secondly, make a reasonable set meal to meet the needs of different consumer groups, and those who have little money can eat well < P > Thirdly, send drinks to the store for free; fourthly, issue coupons at the gate of the food city to guide customers to spend in the store.
