Taking Beijing Capital International Airport as an example, you can go to the Affordable Food City.

As a super-large airport, you can find all kinds of food here, from the high-priced delicacies at Ziyue Restaurant in Terminal 2 to the civilian food street on the basement floor - China Food City.

China Food City sells mostly noodles, such as beef noodles, hot and sour noodles, sausage noodles, fried noodles with soybean paste, etc., which basically cost more than ten or twenty yuan each. It can be said that the price is very affordable.

Convenience stores There are a variety of bento boxes in convenience stores, ranging from junk food to healthy salads. They are basically delivered on the same day. The key is that the price of bento boxes in chain stores in the city is the same.

The bento that costs 10 yuan downstairs at my house is also 10 yuan at the airport.

The same is true for other chain convenience stores, where a bento will rarely cost more than 20 yuan.

Convenience stores have microwaves, and the staff will help heat them up and give you free chopsticks and napkins.
