The name itself (21 grams is a unit of weight sometimes used in bartending for precise pours) signals that the bar takes its craft seriously without announcing it loudly.\n\nThe Cửa Nam ward location is slightly south of the main Hoàn Kiếm lake circuit, which keeps foot traffic intentional. The crowd that finds its way here tends to be a mix of Hanoi locals looking for a neighbourhood bar that isn't a beer garden and visitors who've done enough research to want something beyond the backpacker strip. It works as a first-drink destination before dinner or a last stop after one, and the intimate scale makes it suited to pairs or small groups rather than large parties.\n\nFor cocktail bars in this price bracket and neighbourhood, the rating holding above 4.0 across a meaningful sample of reviews is the clearest signal available — Hoan Kiem has no shortage of options, and sustaining that average requires consistency.",{"Friday":64,"Monday":66,"Saturday":68,"Sunday":69,"Thursday":71,"Tuesday":72,"Wednesday":73},[65],"7:30 PM–2 AM",[67],"7:30 PM–12:30 AM",[65],[70],"7:30 PM–12 AM",[67],[67],[67],"+84 988 111 121",{},"moderate","#C99B4A",4.2,235,{"average_rating":78,"distribution":81,"items":83,"total_count":79},{"1":82,"2":82,"3":82,"4":82,"5":82},0,[],[85,95,102,109,116],{"categories":86,"id":89,"primary_image":90,"rating":91,"slug":92,"title":93},[13,87,88],"Bar","Pub","b84817d8-dab0-4da3-a5db-577bc48c2e59","https://images.thaodien.app/images/leos-tavern/google_maps/cda795e9e790ab75.jpg",5,"leos-tavern",{"en":94,"vi":94},"Leo's Tavern",{"categories":96,"id":97,"primary_image":98,"rating":91,"slug":99,"title":100},[13],"4d21be31-4a01-4e29-bb96-7d703f443ae1","https://images.thaodien.app/images/mutt-a-pub/google_maps/a0871c6c5b1a3e7f.png","mutt-a-pub",{"en":101,"vi":101},"Mutt A Pub",{"categories":103,"id":104,"primary_image":105,"rating":91,"slug":106,"title":107},[13],"77b93027-8728-4b7c-8a16-3c74d9447b0d","https://images.thaodien.app/images/mizumi-sky-lounge/google_maps/2910050377aa5a7d.jpg","mizumi-sky-lounge",{"en":108,"vi":108},"Mizumi Sky Lounge",{"categories":110,"id":111,"primary_image":112,"rating":91,"slug":113,"title":114},[13],"2d830f8d-951c-4b39-a8a1-572b105a0c4b","https://images.thaodien.app/images/velas-sky-bar-managed-by-skyon9/google_maps/311650f6d77d2157.jpg","velas-sky-bar-managed-by-skyon9",{"en":115,"vi":115},"Velas Sky Bar - Managed by Skyon9",{"categories":117,"id":119,"primary_image":120,"rating":91,"slug":121,"title":122},[13,118],"Restaurant","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":123,"vi":123},"Botan Bar & Dine - Rooftop Bar","21gam",{"website":126},"https://lnk.bio/21gamofhanoi","free","21Gam","2026-07-19T06:50:53.059363+00:00",[131,132,133,134],"intimate","low-lit","relaxed","neighbourhood"]
