SkyOn9 Rooftop Bar - Hoan Kiem - Restaurant in Hanoi

Perched above Hàng Trống Street on the ninth floor, SkyOn9 looks directly over Hoan Kiem Lake — one of the few rooftop positions in the Old Quarter that keeps the lake in frame rather than the tangle of wires and shophouse rooftops that fill most Hanoi skylines. The combination of a restaurant, bar, and grill under one roof means the crowd skews mixed: couples working through the cocktail list as the sun drops behind Ngoc Son Temple, small groups splitting grilled plates, and the occasional table treating it as a proper dinner destination rather than just a drink stop.

With 481 Google reviews averaging 4.9 stars, SkyOn9 sits in unusually consistent territory for a rooftop venue in this part of the city, where the format often trades food quality for the view premium. The bar and grill framing suggests a menu built to hold attention beyond a single round — grilled dishes alongside bar snacks rather than the thin appetizer selection common at competitors angling purely for the tourist walk-in.

Hoan Kiem has no shortage of rooftop options, but most cluster around the Ta Hien bar street corridor or face inward over the Old Quarter grid. The Hàng Trống address puts SkyOn9 on the quieter southern edge of the lake, closer to the French Quarter than the backpacker strip, which shifts the atmosphere toward a slightly older, less transient crowd. The address at number 36 is straightforward to find, sitting just off the lake's western walkway.
