Kalt Kalteo Kalteu is a brunch restaurant in an alley near Noksapyeong Station in Seoul, serving coffee, French toast and desserts. The menu includes coffee with honey butter toast and caramel pudding. The space sits deep in the alley and is set up for enjoying the room and the music together. The cafe is hard to find, so taking the footbridge at Noksapyeong Station avoids the hill.
