Alcheon Seongdong Main Branch Gopchang Jeongol is a restaurant in Seoul that serves Hanwoo gopchang, makchang, chadolbagi, and gopchang jeongol. The gopchang jeongol uses a lot of chili, making it spicy and pungent, and grilled gopchang is sold as well. The gopchang contains a lot of gop and has almost no odor. The flavor is not particularly impressive and is ordinary, which is a disappointing point.
