Oreno Ramen Lotte World Mall is a Japanese ramen shop in Jamsil, Seoul, serving chicken-broth ramen including tori paitan and kara paitan. Tori paitan uses a rich chicken-based broth, while kara paitan adds spice to the soup and is paired with thin, firm noodles. Noodles, rice, and broth can be refilled for free, and customers pay in advance at a kiosk near the entrance before waiting for their number. Waits run 15 to 30 minutes at weekday lunch and about an hour at weekend lunch.
