>>5 kimbab :) It's super good, they replace vinegar rice with sesame oil rice. GET IT! you should also try Ddeokbokki if you like spicy food, it is VERY popular within tourists and local people as street food. You also have to absolutely try Hoddeok, which is a type of pancake that has either brown sugar or japchae (potato noodles) inside of it and they're super good.
JUST EAT ALL THE STREET FOOD TRUST ME I'VE BEEN THERE AND IS 100% KOREAN. THEY'RE ALL GOOD.
