Mullino Espresso Bar Yongsan I'Park Mall is a large espresso bar in Yongsan I'Park Mall that sells coffee and desserts. Through its full-length and round windows, it looks out over the cluster of high-rise buildings in front of Yongsan Station. It opens at 10:30 a.m. on weekends, and even though the store is large, there can be a wait when crowds gather. There is spacing between seats, but no partitions, so when many customers are present the sound echoes loudly and it is noisy.
