Jeonju Sundae Guk is a sundae guk restaurant in an alley across from Jungang Market in Sindang, Seoul, making its own pi sundae. The pi sundae guk has a thick, dark broth with pi sundae and offal, and the pi sundae is eaten dipped in chojang mixed with perilla seed powder. Pi sundae is made on Saturdays, and on one Saturday at 6:10 a.m. the shop was full with about a 40-minute wait, while water and side dishes are self-service. The shop has about five tables, and the owner alone handles cooking and serving, so orders and table clearing are slow.
