Food served to participants:
- Lunch Box: This is the first meal served to the participants in the game. It is topped with a fried egg on top of rice, and it consists of common bento side dishes in Korea, such as stir-fried kimchi, stir-fried anchovies, and bean jam. This reminds participants of their ordinary past and serves as a device to further contrast them with the reality of being in a harsh environment.
- Hard-boiled eggs and cider: served as a snack to participants during the game. Due to the insufficient amount, it can also be a factor that causes conflicts among participants.
- Steamed potatoes and corn: Also served as a snack, it is a nostalgic reminder of the poor past.
- Grilled mackerel: It appears in the second half of the scene where Gi-hun shares the mackerel he got from Sang-woo's mother with the participants. It is portrayed as a warm food that makes you feel human warmth, even for a moment.
- Steak: This is a gourmet food served to the winner after the last game. It is a symbolic dish that shows the stark contrast between the participants.
Foods that appeared in the game:
- Dalgona: This is a key food that appears in the second game, 'Dalgona Gacha'. It is a simple sugar cake, but it is used as an important material to maximize the fate and tension of the participants. Circles, triangles, stars, and umbrella-shaped dalgonas appear, and you must pull them out in shape without breaking them within the time limit.
- Ramen: There is a scene where Seong Gi-hun breaks raw ramen as a snack for alcohol. This is a popular food, but it has received attention overseas along with the global popularity of the drama.
