Keik Hauseu Emma is a local bakery in a shopping area of an apartment complex near Gangbyeon Station in Kwangjin-gu, Seoul. It sells sogeumbbang, keuruwasang, and meokmul soseji ppang, which contains ink and has a savory, salty taste. Customers buy keuruwasang instead when the sogeumbbang is sold out. By around 6:30 p.m., nearly all the bread is sold out.
