The address puts diners inside Phố cổ Hà Nội proper, within walking distance of Hoàn Kiếm Lake, which means the clientele skews toward travelers who have done their research alongside Hanoi residents marking occasions that call for more than a street-food crawl. The fine dining designation signals tablecloths and pacing rather than the quick-turn model that defines most Old Quarter eating. Vietnamese restaurants at this tier in Hoan Kiem tend to split between heritage cuisine elevated through plating and modern fusion that reaches for a broader audience; Cloud Nine's classification as a Vietnamese restaurant alongside the fine dining tag suggests the kitchen stays grounded in local cooking rather than drifting into internationalized fusion. For visitors comparing options along the tourist corridor between the lake and the night market, the rating differential matters: at this density of restaurants, a 4.9 across a meaningful review count is a genuine signal. Reservations are advisable for weekend evenings, when the Old Quarter fills and the better-reviewed rooms book out.",{"Friday":70,"Monday":72,"Saturday":73,"Sunday":74,"Thursday":75,"Tuesday":76,"Wednesday":77},[71],"6:30 AM–10 PM",[71],[71],[71],[71],[71],[71],"+84 24 3929 0011",{"Friday":80,"Monday":94,"Saturday":95,"Sunday":100,"Thursday":102,"Tuesday":106,"Wednesday":108},{"5":81,"6":82,"7":83,"8":84,"9":85,"10":86,"11":87,"12":88,"13":88,"14":89,"15":90,"16":91,"17":92,"18":93,"19":85,"20":90,"21":88,"22":81},0,88,100,92,65,50,38,34,42,46,53,73,80,{"5":81,"6":88,"7":89,"8":86,"9":89,"10":88,"11":87,"12":90,"13":90,"14":87,"15":87,"16":88,"17":89,"18":90,"19":87,"20":90,"21":87,"22":81},{"5":81,"6":90,"7":96,"8":90,"9":90,"10":97,"11":88,"12":98,"13":99,"14":98,"15":88,"16":96,"17":90,"18":86,"19":86,"20":91,"21":91,"22":81},57,30,26,23,{"5":81,"6":90,"7":101,"8":93,"9":85,"10":90,"11":87,"12":90,"13":86,"14":90,"15":89,"16":89,"17":91,"18":85,"19":85,"20":92,"21":91,"22":81},61,{"5":81,"6":101,"7":103,"8":85,"9":96,"10":97,"11":104,"12":105,"13":98,"14":97,"15":87,"16":86,"17":92,"18":93,"19":101,"20":89,"21":88,"22":81},84,19,15,{"5":81,"6":98,"7":87,"8":91,"9":87,"10":87,"11":98,"12":88,"13":87,"14":90,"15":90,"16":89,"17":90,"18":91,"19":85,"20":92,"21":107,"22":81},69,{"5":81,"6":89,"7":86,"8":96,"9":86,"10":90,"11":90,"12":89,"13":87,"14":87,"15":97,"16":88,"17":86,"18":93,"19":103,"20":93,"21":101,"22":81},"upscale","#C99B4A",4.9,729,{"average_rating":111,"distribution":114,"items":115,"total_count":112},{"1":81,"2":81,"3":81,"4":81,"5":81},[],[117,127,134,142,149],{"categories":118,"id":121,"primary_image":122,"rating":123,"slug":124,"title":125},[119,120,14],"Bar","Lounge bar","95d7bb83-e2aa-45a1-8cd5-d2665efa197b","https://images.thaodien.app/images/upper-haven-sky-bar/google_maps/ad35b90e5744f42a.jpg",5,"upper-haven-sky-bar",{"en":126,"vi":126},"Upper Haven Sky Bar",{"categories":128,"id":129,"primary_image":130,"rating":123,"slug":131,"title":132},[14],"b20ede8d-1dfd-43a0-b7be-e1476e8a15fa","https://images.thaodien.app/images/lessence-de-cuisine/google_maps/4be3c41820ab5ada.jpg","lessence-de-cuisine",{"en":133,"vi":133},"L'essence De Cuisine",{"categories":135,"id":137,"primary_image":138,"rating":123,"slug":139,"title":140},[136,14],"Cocktail bar","8c95d43e-7780-4d67-b6b5-e11465cc8879","https://images.thaodien.app/images/botan-bar-dine-rooftop-bar/google_maps/dab41a051d4664cc.jpg","botan-bar-dine-rooftop-bar",{"en":141,"vi":141},"Botan Bar & Dine - Rooftop Bar",{"categories":143,"id":144,"primary_image":145,"rating":123,"slug":146,"title":147},[14],"51ac4377-1f96-4f7b-b713-55bc87af6d3c","https://images.thaodien.app/images/shining-view-restaurant/google_maps/8d2ce6d15642a377.jpg","shining-view-restaurant",{"en":148,"vi":148},"SHINING VIEW RESTAURANT",{"categories":150,"id":151,"primary_image":152,"rating":123,"slug":153,"title":154},[14],"a9e84fe6-e772-4eda-8797-e8fe0b770192","https://images.thaodien.app/images/bun-cha-22-ngo-huyen/google_maps/0a6fccbb67bf8f7a.jpg","bun-cha-22-ngo-huyen",{"en":155,"vi":155},"Bún chả 22 ngõ Huyện","cloud-nine-restaurant-hanoi",{"website":158},"https://hanoi.cloudninerestaurants.com/","free","Cloud Nine Restaurant Hanoi","2026-07-19T06:22:57.394088+00:00",[163,164,165,166],"refined","intimate","unhurried","atmospheric"]
