Trill Rooftop Cafe in Hanoi, Vietnam

Trill Rooftop Cafe is a large rooftop café on the 26th floor of Hei Tower at 1 Ngụy Như Kon Tum in Thanh Xuân, Hanoi. It is best suited to travelers who want a high-rise city view with coffee or a meal, couples looking for an evening setting, and groups who prefer a spacious indoor-outdoor venue rather than a compact street café. Current Tripadvisor, Viet-Biz, Foody and 2026 restaurant listings all continue to place Trill at the same Hei Tower address. Its main appeal is the elevated setting, while its main practical limitation is inconsistency between current sources on exact opening hours, phone numbers and some facility details.

The rooftop position is central to the experience. Tripadvisor describes Trill as an open-air, nature-friendly space on top of a 26-storey building, and current Hanoi café guides continue to emphasize broad city views from the roof. Wanderlog’s current listing specifically mentions views across Thanh Xuân with distant high-rise landmarks, while recent visitor material describes both indoor and outdoor seating. The result is a venue that works differently depending on weather: the outdoor areas are the obvious choice for the skyline, but indoor seating is useful during heat, rain or high humidity.

The café is part of a broader rooftop complex rather than a simple coffee counter. Current and recent sources repeatedly associate Trill with dining, events and a swimming-pool area. A 2026 visitor entry describes using the pool and paying a separate admission charge that included a towel, which is useful evidence that the pool remains active within the complex. That should not be confused with ordinary café access, however. Pool use, event bookings and café seating may operate under different conditions, so visitors who specifically want to swim should confirm the current pool fee and access rules before going.

Food and drinks cover more than standard coffee. Tripadvisor categorizes the café with European and Asian food, while Foody currently presents it as a restaurant and café with Western dishes and a broad price range. Recent Hanoi café guides mention coffee, tea, juices, mojitos, yogurt and ice-blended drinks, alongside a more substantial food menu. Because no current official menu with a full date-stamped price list was found in this research cycle, those categories are more reliable than quoting individual dishes as guaranteed. Trill is therefore a reasonable choice for either drinks or a longer meal, but anyone going for a specific item should check the menu on arrival.

The setting is large by café standards. Current Hanoi guides describe a spacious rooftop complex, and older but consistent descriptions place both indoor and outdoor seating around landscaped or decorated areas. That scale helps explain why the venue is also used for events, dates, group gatherings and photo sessions. It is not necessarily a quiet specialty-coffee room: the rooftop concept, event role and pool area can make the atmosphere livelier, particularly later in the day or during organized functions. Visitors wanting uninterrupted laptop work may find quieter cafés more predictable, while people prioritizing scenery and space are more likely to appreciate Trill.

Opening hours are well documented but not perfectly consistent. Tripadvisor and Viet-Biz currently show 08:00–23:00 every day. Foody shows 07:00–22:30, RestaurantGuru lists 09:00–22:40 on weekdays and 08:00–22:40 on weekends, and Tôi Đi Cafe gives 08:30–21:00. Since Tripadvisor and Viet-Biz agree on 08:00–23:00 and both use the current Hei Tower identity, that schedule is the most defensible one to publish, with the discrepancy noted. For a normal afternoon or early-evening visit the difference is not important; it matters if you plan to arrive near opening or stay very late.

Phone information also varies. Viet-Biz lists both 024 3203 4999 and 091 673 38 38. Tripadvisor displays the mobile number, while RestaurantGuru uses the landline. Current secondary guides often use 0916 733 838, which is the same mobile number in a different spacing format. The safest practical approach is to keep both current Viet-Biz numbers and use them to confirm a reservation, event, late visit or pool access rather than assuming one directory is uniquely correct.

Prices depend heavily on how the venue is used. Foody currently displays a broad 50,000–250,000 VND range, RestaurantGuru shows a lower dining range on its listing, and Tôi Đi Cafe gives 40,000–100,000 VND for café spending. These differences likely reflect drinks, meals and different data sources rather than one simple tariff. A 2026 visitor also described a separate pool charge. Visitors should therefore budget by activity: coffee alone may be relatively modest, a meal will cost more, and swimming or events can involve separate fees.

Recent visitor evidence is useful for timing. A 2026 review describing an October 2025 visit said the rooftop pool and view were particularly pleasant toward the end of a sunny afternoon, while RestaurantGuru includes a 2025 Google-derived comment recommending evening over hot, humid daytime conditions. These are individual experiences rather than universal rules, but they fit the practical reality of an exposed rooftop in Hanoi. Late afternoon into evening is a sensible choice if the skyline and outdoor seating are central to your visit, while midday may be less comfortable in hot weather.

Reaching Trill is straightforward once the correct tower is identified. Use Hei Tower, 1 Ngụy Như Kon Tum, Nhân Chính, Thanh Xuân as the taxi or ride-hailing destination, then follow the building signs to the 26th floor. An older Foody visitor specifically warned that the area can be confusing because nearby buildings have similar numbering, so using “Hei Tower” together with the full street address is more reliable than using only the number. The rooftop is accessed within a high-rise building, but current sources do not provide enough detailed accessibility information to confirm step-free access from the street through every café, event and pool area.

A normal café visit of around one to two hours is reasonable for drinks, food and enjoying the view, while a meal, pool session or event can extend much longer. Trill is not an attraction with a fixed visit duration or admission requirement for ordinary café use. Its value comes from choosing the part of the complex that matches your plan: rooftop coffee and photographs, indoor dining, an evening meetup, or separately confirmed pool access.

Trill Rooftop Cafe is therefore one of the better-documented active rooftop cafés in western-central Hanoi, with a consistent 26th-floor Hei Tower identity and recent evidence of continuing operation. The strongest reasons to go are the city views, large indoor-outdoor setting and ability to combine café service with a broader rooftop experience. The details that require caution are the exact daily timetable, current menu prices, pool charges and accessibility. Use the verified Hei Tower address, aim for late afternoon or early evening if the view matters most, and call ahead when a specific facility or late closing time is important.
