In Korea, it's very easy to find street food carts, selling various popular foods, such as ddukbokkee (rice cakes and eggs with spicy sauce). Around the street carts, students gather around and pick whatever they wish to eat and save a lot of their money at the same time.
In Korea, Karaoke has been very popular and became part of their culture. Especially, students love to go with their group of friends and spend 1 to 2 hours of singing. In past, Karaoke was a place just for singing, however, nowadays, it has been advanced and there are more activities to do, such as taking sticker photos, which I will explain next.
These are sticker photos that I took in Korea. They are usually $7, and there are various machines with different qualities. After taking pictures, you can decorate and add many quatities as much as you want.
