One & Only 원앤온리

One & Only is a large ocean-view cafe on Hwanguchi Beach at the foot of Sanbangsan in Andeok-myeon, Seogwipo-si, Jeju. The magnificent rock face of Sanbangsan rises directly behind the building while an unobstructed sea stretches out in front, forming a landscape that defines the entire visit. The setting evokes a Southeast Asian resort, and the venue offers a two-story interior, a rooftop, and expansive outdoor seating that flows toward the beach, presenting a fresh view from every angle. A LUSH cosmetics shop is built into the premises, giving visitors the unusual option of browsing products after a shoreline walk. Beyond standard cafe drinks, the menu extends to brunch items including eggs benedict and black pork tomato pasta; the flavors lean slightly sweet overall but are enjoyable. Coffee and cake meet a serviceable standard that pairs well with the scenery. Drinks and desserts carry premium pricing, yet the extraordinary natural panorama surrounding the cafe generally justifies the surcharge. Parking is spacious and vehicle access is convenient, but during peak season the volume of visitors gridlocks traffic in the surrounding area. Indoor seating is limited relative to the overall footprint, so securing a table is not always straightforward. During crowded periods, the atmosphere suits photo-taking and scenery appreciation more than quiet conversation. Operating hours are 10:00 AM to 6:40 PM daily, with last orders at 6:00 PM.
