Cafe Doubleton is a cafe on the third floor of an unremarkable building near Chungmuro Station in Seoul, selling coffee, dessert, and toast. Its signature items are the Double Double cream latte and hand-drip coffee, and it also serves kaya toast. Reaching the third floor requires climbing a long, high staircase, and the interior is dark, quiet, and spacious. The building's exterior does not look like a cafe, which makes the entrance hard to find.
