I’ve deeply recommended Deep dark blended (10/10). It was balanced sour and bitter. I came here because this is a coffee roaster so this place is smell so good. The shop is nearby exit 1 of Mangwon market

What at first glance appears to be a bottom feeder's paradise, this reverse iceberg inspired revelation-by-revelation patron space allows its little fishies to spelunk unchartered corners level-to-level. Following the predictable trend of pastel dehydrated flowers in lineated window outlooks, this little piece of carmalized cream a top the foundational set of plump naturally sweetened pumpkin pie provides a pleasure packed jazz hand waving in the symbolic heart. Flatwhite is Jam.

Amazing coffee and fantastic staff. I had a great conversation with the owner, who has extensive experience in coffee from around the world, including some of the top cafes in Melbourne, Australia. As a coffee enthusiast from Sydney, I would rate this place 10/10.

Deep Blue Lake — their name truly reflects the service they provide. Their coffee brought me warmth and delight, in a breeze-like place that felt just like home. That doesn’t mean they’re only quiet; they’re also unique. From the entrance, their funkiness is clear, with quirky illustrations combining coffee and the Chinese zodiac. I had a wonderful time there and will definitely visit again!

Quality specialty coffee roasting house. Visited once, after having ordered several packs of beans. 3-4 Baristas are hand picking the bad beans from the freshly roasted batch. High quality roasting(light), with very reasonable price. Not many seats inside, and no filtered coffee is serving.
