Sushi Isei Lotte Department Store Avenuel Jamsil Branch is a Japanese restaurant on the sixth floor of Lotte Department Store Avenuel Jamsil in Songpa-gu, Seoul, serving sushi and omakase. Its assorted sushi comes with flounder, sea bream, salmon, tuna, and shrimp, along with futomaki and buckwheat noodles, while the seasonal fish omakase serves aburi nigiri and a clear soup course in sequence. The room lunch course is booked in advance through CatchTable and eaten in a private room. The lunch course has a 1-hour-10-minute dining limit, which makes long conversation difficult.
