Ashley Queens Changdong Seed Cube is a family restaurant on the third floor of Seed Cube Building A, a two-minute walk from Changdong Station Exit 1. It runs as a buffet with sushi, Asian food, Western dishes, salads, and desserts, including corn sushi and soy sauce shrimp sushi. The dining time is two hours, robots collect the plates, and parking is available in the building. The indoor paths are narrow, so you overlap with the robots when getting food.
