Lotteria Yongsan Station ST is a small fast-food spot inside Yongsan Station selling hamburgers and french fries. Orders are placed at kiosks for items such as Misshapen Potato, fried squid, shrimp burger, and T-Rex. Two self-order machines sit at the entrance, and most seating is for single diners, which suits a quick meal or takeout before a train. When the store is busy, burgers can come out lukewarm.
