Liu Riu Quán in Hanoi, Vietnam

Liu Riu Quán is a Vietnamese restaurant at 02 Yên Thái in Hanoi’s Old Quarter area, currently operating under the name “Liu Riu Quán” rather than the older English-facing “Liu Riu Hanoi” label. The current claimed Tripadvisor profile identifies the same Yên Thái address, publishes daily hours and lists Vietnamese and Asian cuisine, while a separate mapping source still links the business to the liuriuvietnamesecuisine.com domain used in earlier years. The continuity of address, concept and website trail supports treating this as the same restaurant entity. For visitors, the practical identity is simple: look for Liu Riu Quán at 02 Yên Thái and do not depend on the exact English wording of the old Travel S Helper title.

The restaurant’s current profile focuses on lunch, dinner and drinks, with vegetarian, vegan and gluten-free options listed among the dietary categories. It also shows reservations, table service, takeout, Wi-Fi, wine and beer, and highchairs. Those features make Liu Riu more flexible than a single-dish street stall, especially for mixed groups. At the same time, the available current sources do not publish a complete operator menu in crawlable text, so it would be misleading to present a fixed list of signature dishes as if it were guaranteed today. The managed Tripadvisor listing illustrates dishes such as grilled beef with lemongrass and banana-flower chicken salad, but travelers should use those as examples of the restaurant’s Vietnamese style rather than a promise that each item is always available.

An older 2020 feature described Liu Riu as a place for home-style Vietnamese food served in an old Hanoi house, with both indoor rooms and an open-air garden area. That background is useful because it explains the restaurant’s longstanding concept, but it should be treated as historical context rather than proof that every decorative detail remains unchanged in 2026. The current listing still shows an interior-focused, sit-down restaurant rather than a takeaway counter, and the Yên Thái address has remained stable. Visitors interested in a traditional-house atmosphere can reasonably consider Liu Riu, but anyone choosing a specific courtyard table or garden setting should ask at reservation time rather than relying on a six-year-old description.

Current hours are 11:00 to 22:00 every day according to the business-managed Tripadvisor profile. This makes the restaurant easy to use for either lunch or dinner and avoids the afternoon closure common at some fine-dining venues. A reservation is not always necessary, but it is sensible for a group, a special occasion or peak evening time. For an ordinary meal, allow roughly 60–90 minutes; shared family-style dining or a group ordering many dishes can take longer. The restaurant’s currently published phone number on Tripadvisor is +84 33 816 5486. Some older sources show a different hotline, so present-day visitors should use the current managed listing or website contact rather than relying on a number saved from an older blog post.

The location is highly convenient for an Old Quarter day. Yên Thái is a small street west of Hoàn Kiếm Lake, within walking range of many central sights and hotels. Because the lane network can be confusing for first-time visitors, navigation is easier with the exact address than with the restaurant name alone. Taxis and ride-hailing vehicles may drop passengers on the nearest practical street rather than directly at the door if traffic or pedestrian conditions are restrictive. The central location also means parking should not be assumed. Travelers already exploring the cathedral, lake or western side of the Old Quarter can fit Liu Riu into a walking itinerary without dedicating a separate cross-city transfer.

Dietary labeling deserves a careful reading. The current listing identifies vegetarian-friendly, vegan and gluten-free options, which is useful for groups, but it does not establish a certified gluten-free kitchen or explain cross-contact procedures. Guests with coeliac disease, severe allergies or strict vegan requirements should ask staff about sauces, fish sauce, shared cooking surfaces and preparation methods. Payment information on the current Tripadvisor profile is also internally inconsistent because it lists both credit-card acceptance and “cash only” among features. That contradiction is exactly the kind of volatile practical detail that should be confirmed at the restaurant. Carrying some Vietnamese cash is prudent even if digital or card payment is expected.

Liu Riu’s main strength is that it offers a broader, seated version of Vietnamese home-style dining in a location that is still convenient for tourists. It is less formal than Hanoi’s hotel fine dining and more structured than eating from a street stall. Travelers who want an extensive wine program or tasting-menu choreography should choose a different restaurant; those who want several Vietnamese dishes at one table, vegetarian flexibility and a central Old Quarter address are a better fit. Because the current online footprint is thinner than that of larger hotel restaurants, visitors who care about a particular dish, private room or event arrangement should contact the restaurant directly instead of inferring details from photographs.

Treat Liu Riu as an active, established Hanoi restaurant whose branding has shifted slightly but whose core identity remains recognizable. Use 02 Yên Thái, plan around the 11:00–22:00 daily schedule, and confirm payment or dietary details if they are important. The current evidence supports publishing the restaurant as active, but it also argues for restraint: old blog descriptions are useful for history, not for claiming today’s exact décor or menu. That distinction lets visitors understand what Liu Riu reliably offers—a central Vietnamese restaurant with sit-down service and multiple dietary options—without turning older promotional material into unsupported present-tense promises.
