Our Neighborhood Sushi Shinjo Gangnam is a conveyor-belt sushi restaurant on the third floor near Gangnam Station, serving salmon, flounder, sea bream, yellowtail, mullet, and uni sushi. Diners pick plates off the rotating belt or order sushi such as ankimo and mackerel on a tablet, and the items arrive at the seat by rail. Empty plates go into a return slot, the tablet shows the count, and the bill is paid at the seat. A separate lunch menu is available.
