Not all halal restaurants use Pepsi-Cola, and some halal restaurants use Coca-Cola or other drinks.

In Islam, alcoholic beverages are considered unclean, so halal restaurants usually avoid alcoholic beverages and choose to use other beverages instead. In addition, some halal restaurants may also use drinks such as Coca-Cola to meet the needs of local consumers because these drinks are more popular in the local market.

It should be noted that although some halal restaurants use Pepsi or other drinks, this does not mean that all halal restaurants are like this. Therefore, if you want to know more about halal restaurants, it is recommended that you learn more about the local market or ask locals about their eating habits and preferences.
