There are cafes and tea restaurants, but it is expected that there will be places to eat, and there will be no consumption like KFC and McDonald's.

Expensive.

There are some delicious foods in it, such as Harbin Red Square, Da Lieba and so on. But the price is also very expensive.

You can eat something near the airport bus before you go to the airport. But there is no specific restaurant. I suggest you go to Nangang to eat first. Both KFC and McDonald's have them. Then you can take a taxi or bus to Swan Hotel, where there is an airport bus. Then go to the airport.
