When I visited Korea this year, my eyes always saw a lot of food street vendor selling various kinds of Korean snack in Seoul. It looked like a covered wagon or small wagon covered by tent with ajumha was busy with her tteokpokki and other delicious snack inside the tent. I just know that the name is food street vendor but now I know that the Korean name is Pojangmacha 포장마차.
It sells a variety of popular street foods such as hotteok, gimbap, tteokbokki, sundae, odeng, gimari, kimbab and I can find soju also. There are some benches for customers to seat but sometimes customers just stand for eating quickly. It is the most favorite place to eat and drink into the night in Korea ^^
