The security check is on the departure floor (that is, 3F). There are Costa and Starbucks outside the security check, McDonald's and Longji Hong Kong-style tea meals 20 meters away, and the most famous Viennese coffee in Europe. If you want to eat KFC and Yonghe soybean milk, you have to get off the elevator to the 1F floor.

There are also a lot of food in the security check, such as McDonald's, Kung Fu, and some noodle restaurants, buffets and subway. . .

Airport bus? It seems that the terminal is the place to get off, but you have to take the elevator to the 3F departure floor.
