Grab a Seat in Eatery Alley
There's a small street in the shopping nexus of Nampo-Dong filled with stands offering a cheap outdoor lunch. Hot noodles, kimchi, rice bowls, tteokbokki (a spicy rice cake dish), all served up by a colorful collection of Korean lunch ladies. The map refers to this as "Eatery Alley", which is about as accurate a name as possible.
