Esso is a cafe on the second floor near the middle of Gwangalli Beach in Busan, serving espresso, coffee, and Einspänner. The Einspänner uses beans with almost no acidity and is finished with cocoa powder for a sweet drink. It opens at 9 a.m. and closes at 11 p.m., with the last order at 10:30 p.m. The restroom near the order counter smells and the trash bins overflow.
