Isak Toast Changcheon is a takeout-focused toast shop in an alley next to a fruit and vegetable store at the Hongdae Donggyo-dong three-way intersection in Seoul. The basic toast comes with bacon and a fried egg, and you can order it with less sauce so the nutty bread and butter flavors come through. Orders come out quickly, and there are simple tables outside the store. There is not enough seating space to eat inside.
