"Definitely one of the BEST cafes in Korea! I visited during my trip with my friends and we loved every part of it! The interior is super cute and well decorated to be ocean themed and there’s a really nice space to sit upstairs that feels so immersive. We ordered matcha lattes and tried a couple of their pastries and it was all super delicious! I would highly recommend if you’re looking for a cute themed cafe in Korea :))"
