Eun & Jeong Budae Jjigae
Open in Google Maps Spam-and-ramyeon "army stew" done with a Seoul polish.
Budae jjigae was invented from US Army surplus after the Korean War, Spam, hot dogs, baked beans, kimchi, ramen, all bubbling in red broth.
Eun & Jeong is the foreigner-easy Myeongdong version.
(For the original spirit, take a 30-min train to Uijeongbu.)
