Blanc Rocher
Tucked away in a cove in northeastern Udo Island, this cafe opens its window walls when the weather is nice, letting in the ocean breeze. Udo Island is renowned throughout Korea for its peanuts, a fact reflected in the menu starring peanut ice cream, lattes with peanut-flavored milk, peanut cheesecake, and even jars of peanut jam. Non-peanut beverages are available, too, including a smoothie made from Jeju hallabong. The minimalist white interior distracts little from the seaside scenery, though if you really want to embrace the surroundings, take a seat on the outdoor terrace.
