Tiumsaeramyeon is a ramyeon snack shop in Yeouido, Seoul, open 24 hours in front of the KBS main building. Its signature dishes are spicy ramyeon with egg or seafood, such as ppalgyettaek and ppalhaettaek, and the rabokki comes with a whole pack of ramyeon. The spice level is strong enough to bring tears, and the 24-hour schedule means you can eat late at night. Seating inside is on the narrow side.
