Idiya Yeosu Hanjae DT is a drive-through cafe on the Hanjae hill past the Hanjae Tunnel in Gwangmu-dong. You order a strawberry smoothie on the first floor and drink it on the second floor while looking down at the Yeosu sea and the old downtown. The parking lot is large, the store is big, and there are second-floor outdoor tables and a rooftop. The interior is kept clean and absorbs sound well.
