Ilgwang Jjokgalbi in Seoul serves only jjokgalbi, a single menu item. The meat is grilled to order and has a salty, smoky flavor. A wait forms in the evening, but by around 5 p.m. you can walk in without waiting, and takeout has been available since the pandemic. The portions of jjokgalbi are small, so two people need at least three servings for a first meal.
