Hei Coffee is a small cafe in an alley within walking distance of Exit 4 of Hyehwa Station in Seoul. It sells cake, coffee, and milk tea, including corn Basque cake, mugwort cake, and cafe latte, with a decaf option available. On weekend afternoons the shop sometimes has no wait, but at 2 p.m. there are no seats and the wait can run about 30 minutes. The store is cramped, the chairs are very uncomfortable, and the restroom is inside.
