Outside. According to the map of Gaode, there are many delicious foods around Jiaodong Airport Building. There are no kinds of food for sale at the airport security check, so we need to go out and buy them. Among them, KFC is located outside the security check, between the 3 rd and 4 th entrances of Terminal 1. KFC's hamburgers, chicken wings and other solid foods can pass the airport security check, while liquid foods such as beverages cannot pass the airport security check.
