Sadhu Vegetarian Restaurant – Lý Thường Kiệt in Hanoi, Vietnam

Sadhu Vegetarian Restaurant at 87 Lý Thường Kiệt is the Hoàn Kiếm branch of a Hanoi vegetarian restaurant group that now also lists locations at Hoàng Đạo Thúy and Lotte Mall West Lake. The Lý Thường Kiệt branch operates as an all-you-can-order vegetarian dining experience rather than a conventional self-service buffet: diners select many small dishes from a large menu and staff bring them to the table. It suits vegetarians, vegans who are willing to identify suitable dishes, and omnivores who want to explore Vietnamese plant-based cooking in a polished environment. The main practical consideration is time: the format encourages sampling many dishes, so a meal can run well beyond a quick one-hour lunch.

The 87 Lý Thường Kiệt address is just south-west of the Old Quarter core, still central but outside the narrowest tourist lanes. The official Sadhu site lists the branch, phone number and two other Hanoi locations, which helps distinguish this entity from the newer branches. Travelers should specify “Sadhu Lý Thường Kiệt” when booking or using ride-hailing so they do not end up at Lotte Mall or Hoàng Đạo Thúy.

Sadhu’s concept is vegetarian Vietnamese cuisine presented in a serene, contemporary setting. The restaurant’s own language connects the name “Sadhu” with benevolence and a wish to offer rest and well-being through vegetarian food. Tripadvisor categorizes the branch as Asian, Vietnamese and healthy, and recent 2026 visitors describe an extensive selection served in repeated small plates. The experience therefore resembles a tasting exploration more than ordering one large main course.

The menu is broad. Current secondary sources describe more than one hundred vegetarian choices across Vietnamese and Asian styles, including mushroom dishes, soups, dumplings, rolls and desserts. HappyCow describes most dishes as vegan-friendly while noting that some items may contain cheese or cream. That distinction matters: Sadhu is a vegetarian restaurant, not automatically a fully vegan kitchen. Vegan diners should tell staff clearly that they avoid dairy and other animal-derived ingredients rather than assuming every plate is vegan.

The buffet model is also easy to misunderstand. Guests do not necessarily walk along a buffet counter loading a plate. Recent visitor accounts describe ordering from the menu and receiving multiple small dishes at the table, allowing diners to try many preparations without committing to full portions. This makes Sadhu particularly good for groups willing to share and compare. It also creates a risk of ordering too much too quickly, so first-time visitors may prefer to begin with a smaller selection and add dishes gradually.

Current hours are consistent across strong sources: 10:30 to 22:00 every day. Tripadvisor’s Lý Thường Kiệt page and other current listings agree on that schedule, and recent May and June 2026 reviews confirm active operation. Reservations are advisable, especially on weekends and on lunar-calendar vegetarian days when demand can rise. Recent visitors specifically recommend booking to avoid waiting.

The meal is relatively expensive compared with a simple vegetarian noodle stall, but the comparison should be with a large-format tasting or buffet experience. A current Hanoi guide places the per-person range around VND 300,000–400,000, while recent visitor reports mention buffet pricing in a similar band. Those numbers can change, so they should be treated only as planning guidance. Drinks may be additional, and visitors should check the current package when booking.

Allergy and dietary communication remains important even in a vegetarian restaurant. Nuts, soy, gluten, sesame, dairy and mushrooms can appear across many dishes. A 2025 HappyCow reviewer reported that staff proactively asked about restrictions, but an individual account cannot guarantee the same process on every visit. Guests with serious allergies should state them at the start and ask which dishes can be served safely. People requiring a strictly vegan meal should request vegan selections explicitly.

A realistic visit duration is around one and a half to two and a half hours, depending on how many rounds are ordered. The format rewards a relaxed meal and is less suitable for travelers rushing between timed attractions. The branch is easy to combine with central Hanoi museums, government-quarter streets or the Old Quarter, but it is best scheduled as a main meal rather than squeezed into a short gap.

Sadhu’s strongest appeal is range: one sitting can introduce a traveler to many textures and Vietnamese vegetarian ideas without requiring knowledge of dozens of dish names in advance. Its calm setting and table-delivered buffet style make it accessible to newcomers, while the large menu gives experienced vegetarian diners plenty to explore. The tradeoffs are a longer meal, higher cost than street food and the need for vegans to identify suitable dishes carefully. For travelers who want plant-based Vietnamese dining as an experience rather than a compromise, the Lý Thường Kiệt branch is one of Hanoi’s most substantial options.

Because the operator now has several Hanoi branches, saved maps and older recommendations can easily point to the wrong Sadhu. Checking the branch name before departure is therefore more important than it appears, especially when meeting other people for a reservation. The Lý Thường Kiệt branch is the entity covered here.
