Chop Chop Lotte World Mall is a Vietnamese restaurant on the B1 floor of Lotte World Mall in Jamsil, across from Lotteria in the inner section. Its signature dish, Chop Chop noodles, mixes peanut sauce with plump shrimp and onion for a lightly spicy, nutty flavor. A wait forms even at weekday lunch, but the restaurant is relatively quiet before 11:30 AM. When no table is available, orders can be placed directly at the free seating area in front.
