Eulji Self Ramen is an unmanned electronic ramen convenience store on the basement first floor of the Eulji Biz Center in Euljiro, Seoul. Customers pick a ramen such as Ojingeo Jjamppong or Shin Ramyun Geonmyeon, add free toppings, and boil it themselves. It is open 24 hours, and the machine automatically sets the water amount, boiling time, temperature, and doneness. An instructional video is available so first-time visitors can check how to use it.
