Why here

A sandwich counter tucked into a residential block in Changjeon-dong, close enough to Hongdae to be walkable but hard enough to find that most people arrive with directions open. Four or five sandwiches at a time — egg omelette with sriracha on brioche, mashed potato on baguette, grilled pesto with mozzarella — between ₩9,000 and ₩12,000.
