Location
The map marks Dumulmeori itself, not a specific hotdog shop or car park.
The wide river and the trees were enough reason to slow down here. I liked walking by the water without a packed sightseeing plan, then stopping for a hotdog.
The snack I remember
We tried a mild and a spicy hotdog. The menu I photographed listed them at ₩4,000 each. The crisp coating and substantial sausage made it more filling than I expected.
There are several food stalls around the area. Use the shop sign and menu to identify the place you want, rather than relying on similar names.
Leave time for the journey
We drove, and leaving the parking area took much longer than I expected. That was the practical downside of the visit. Check parking fees and current traffic rather than assuming every lot is free.
If using the train, Yangsu Station is the starting point to check on your map; allow for the remaining walk or local transport. For lotus flowers or a Semiwon visit, check seasonal conditions and opening information separately.
