The DIOS in Hanoi, Vietnam

The DIOS is a cocktail bar at 76 Tuệ Tĩnh in Hanoi’s Hai Bà Trưng district, in the Nguyễn Du area south of central Hoàn Kiếm. Fresh 2026 research supports keeping it as an active Travel S Helper venue. Tripadvisor’s current claimed business profile still lists the exact address, telephone number and daily evening hours, while several recently crawled Vietnamese directories independently continue to describe The DIOS at the same location. It suits travelers who want cocktails, spirits, music and a polished lounge-bar atmosphere outside the Old Quarter’s busiest nightlife lanes. The main practical caveat is that current opening times differ sharply between sources, so anyone planning a very early or very late visit should verify directly before going.

The venue’s identity is unusually stable across the current sources. Tripadvisor lists The Dios at 76 Tuệ Tĩnh, Nguyễn Du, Hai Bà Trưng, with phone +84 812 100 202. Mytour, updated in the current 2026 search cycle, gives the same address, phone and contact identity. Viet-Biz also lists 76 P. Tuệ Tĩnh and the same 0812 100 202 number, together with the email thedios.hn@gmail.com. Those repeated details make the original WordPress route to Hanoi reliable and give no reason to treat The DIOS as a moved or duplicate entity.

The bar’s branding is built around Greek mythology. Current and recent directory descriptions continue to reference a mythological theme, while older promotional material named cocktails after figures such as Zeus, Hades, Hypnos, Eros, Demeter, Persephone and Ares. These names help explain the venue concept but should not be published as a guaranteed 2026 menu. Drink lists change, and no current operator-controlled menu was available during this research cycle. The useful expectation is simply that cocktails and spirits are central to the experience.

Tripadvisor is the strongest source for current hours because the profile is marked “Claimed,” meaning someone associated with the business manages it. The page lists 20:00–02:00 every day of the week and describes dinner, late-night service and drinks. It also lists live music, reservations, alcohol service, wine and beer, free Wi-Fi, digital payments and street parking. The profile has no published traveler reviews, so those details are operator-supplied listing information rather than an independent pattern of recent guest experience.

Other current sources create a significant hours conflict. 9Life lists 18:00–02:00 daily, while Tôi Đi Cafe currently shows 07:00–23:00, and Viet-Biz claims the venue is open 24 hours every day. Mytour and Golook also repeat all-day or broad operating windows in some versions of their content. These schedules cannot all be correct simultaneously. The claimed Tripadvisor timetable is therefore the best-supported choice for the sidebar, while the discrepancy must remain visible in research notes. Travelers planning to arrive before 20:00 or stay close to closing should call the venue first.

The bar appears to sit somewhere between a lounge, pub and nightlife venue rather than a high-volume nightclub. Tripadvisor classifies it as a bar, pub and dining bar, while 9Life lists Cocktail Bar and Pub categories. Current editorial directories describe a spacious interior, strong sound and lighting systems and an environment intended for music as well as drinks. Because those descriptions are promotional or directory-based, the article should not promise a particular DJ, singer or weekend event without a dated event schedule.

The location is convenient for travelers staying south of Hoàn Kiếm Lake, around Trần Nhân Tông, Bùi Thị Xuân, Phố Huế or the Vincom Bà Triệu area. Visitors staying in the Old Quarter can reach Tuệ Tĩnh by taxi or ride-hailing, while some central hotels are within a comfortable walk. The bar is on a normal city street rather than deep inside an alley, so the final approach should be straightforward. Exact travel times depend heavily on Hanoi traffic and should not be hard-coded into the page.

Pricing information is too inconsistent to use as a firm guide. Some current editorial pages list a broad 150,000–499,000 VND reference range, while other directory pages show much lower ranges that may refer to cafe-style drinks or outdated menus. This variation reinforces the possibility that databases are mixing different dayparts, older menu data or related service concepts. Travelers should ask for the current menu before ordering premium spirits, bottles or large shot trays.

A normal visit is likely to take one to three hours depending on whether the goal is a single cocktail, a social evening or live music. That is an editorial estimate rather than an official recommendation. The 02:00 claimed closing time makes The DIOS suitable for a later night than many restaurant-led lounges, but return transport should be considered in advance, particularly for visitors staying outside Hai Bà Trưng.

Accessibility is not documented well enough for a confident claim. Current sources mention street parking, Wi-Fi and card payments, but they do not confirm step-free entry, accessible toilets or wheelchair circulation. Travelers with mobility requirements should contact the venue directly before going. The same applies to smoking policy, dress expectations, age restrictions and reservations for larger groups.

The DIOS can therefore move from retry to ready status. The strongest facts are consistent: the same 76 Tuệ Tĩnh address, the same phone number, current 2026 directory presence and a claimed Tripadvisor profile with a seven-day schedule. What remains uncertain is not the entity itself but the exact operating window outside the evening period. The page should use 20:00–02:00 as the primary current hours, disclose the conflicting secondary schedules, and avoid presenting old menu items or promotional events as guaranteed 2026 offerings.
