This Korea biz trip I tried something new!  I saw quite a lot of street vendors and they were popular... as a person who is curious of anything new and risky, i did try with my korean colleagues~ 

 

At the vendor, besides this rice cake in red soup, they usually have some deep fried stuffs (like Japanese tempura), some sushi rolls, pig lungs and some rice noodle inside pig intestines... well...i tried all of them!

Tteokbokki (Stir Fried Rice Cake)
Rice cakes are stir-fried with carrots, bamboo shoots, mushrooms, and cucumbers and stewed in scary red sauce/ soup. Anyway I know Korean loves Kimchi and everything looks similar to kimchi.   Although it may sound unappetizing, the taste is very good. It is very popular at street vendors.

 Gimbap (Rice Wrapped in Seaweed)
Gimbap (usually spelled Kimbap) is Korea's most popular and nutritious convenience meal. You can find it sold everywhere: picnics, schoolchildren's lunch boxes, street venders, and convenience stores. 

  

Sundae (Korean Sausage) The small and large intestines of pigs are salted and stuffed with a mixture of pig's blood, rice, green onions, garlic, minced pork, and vermicelli before being steamed. SOUND SCARY huh?!  The sausage is sliced when served and some steamed lung and liver slices usually accompany it.

The pojangmacha (street vendor) is one of the best places to grab a quick snack or pass the night away drinking with friends. The types of food they serve can usually be eaten quickly while standing up (although someplaces have cheap chairs or benches) or take with you.
