Geurang Cafe is a coffee shop in Seoul that serves cold brew, hand-drip coffee, and desserts. Its 20-ounce cold-brew Americano contains 125 milliliters of coffee concentrate and is extracted in a dedicated refrigerator. The shop accepts reservation orders for brewed coffee and cold-brew concentrate at least one day in advance, then roasts the coffee after each order. Hand-drip coffee is sold in limited quantities and may sell out.
