While going around seomyeon or nampodong, you must find the vendor side by side in there. I usually have eaten tokbokki and dumpings. The most delicious one is Seasoned Squid and pancake with soup of fishcake. you can pay just below 10,000 in order to feel full. Although you're worry about food hygiene, It definitely makes you remember unique experience to grab some snack in korea.(You seldom eat like that, so It's okay sometimes you take street food. And It isn't as dirty as you think)
