Hollys Coffee COEX is a coffee shop inside COEX in Gangnam-gu, Seoul, selling coffee, cake, and desserts such as honey bagels. The coffee has a strong bean flavor, and the honey bagels and cakes stand out among a range of desserts. The store is large with many seats and is relatively quiet for a place inside COEX. Orders are placed only through kiosks, which is inconvenient for customers who want to order in person.
