Wat Mangkon Kamalawat and the Nine Days Yaowarat Goes Meat-Free

Wat Mangkon Kamalawat is the most important Chinese Buddhist temple in Bangkok, and for most of the year it is a place of quiet ritual at the centre of Chinatown — incense, gold leaf, fortune sticks. Then, for nine days each autumn, it becomes the epicentre of one of the strangest and best transformations in the city: the Vegetarian Festival, when yellow flags go up the length of Yaowarat and Thailand's most famous street-food road stops serving meat altogether.

The Temple Itself

Founded in 1871, Wat Mangkon — Dragon Lotus Temple, also known by its Chinese name Leng Noei Yi — is the principal temple of Chinese Mahayana Buddhism in Bangkok. Architecturally it is unlike the Thai temples elsewhere on the Old Town route: curved tiled roofs, red and gold, dragon ridge decoration, and a series of shrine halls rather than one central hall.

It is a working temple, busy on ordinary days with people lighting incense, making offerings and shaking fortune sticks. It sits on Charoen Krung Road, a short walk from Yaowarat's main run.

The Vegetarian Festival

The festival — Tesagan Gin Je — runs for nine days, usually falling in late September or October depending on the lunar calendar. Its observance goes well beyond diet: participants abstain from meat, from the five pungent vegetables including garlic and onion, from alcohol, and traditionally wear white.

What makes it remarkable in Bangkok is the scale of the switch. Yellow flags bearing the character 齋 (jay) appear over stalls along Yaowarat, and vendors who sell pork and seafood the other fifty-one weeks of the year convert their entire menus. The street becomes, briefly, one of the best places to eat vegetarian food anywhere in Asia.

Wat Mangkon is the centre of it — the ritual heart, and the busiest point on the street for those nine days.

Jay Is Not Quite Vegan

Worth knowing before you order. Jay excludes meat, seafood, dairy, eggs and the five pungent vegetables. It is stricter than ordinary vegetarian food and, on the garlic and onion point, stricter than most Western vegan cooking too. Food marked with the yellow jay flag is reliably free of animal products during the festival.

What to Expect: Wat Mangkon on the Route

Wat Mangkon is the final landmark on the Thai Bus Food Tour route, closing the loop back through Chinatown. The 1.5-hour journey departs River City Bangkok, Room 163, and passes more than 20 landmarks including Wat Traimit, the Yaowarat Gate, Chinatown, the Golden Mount, Loha Prasat, Democracy Monument, the Grand Palace, Wat Arun, Wat Pho, the Giant Swing and Wat Suthat.

Four rounds run daily: Wonder Lunch 11:30 AM, Sightseeing Afternoon Tea 2:00 PM, Dinner Thai Set 5:30–7:00 PM at 1,890 THB per person, and Bangkok Nightlife 7:30 PM. The evening rounds show Chinatown with the neon on, which during the festival means neon and yellow flags together.

Vegetarian, vegan and halal sets are available year-round — not only during the festival — and are prepared in advance when you tell the team at the time of booking. For the full picture see the vegetarian food tour in Bangkok, and for the neighbourhood's history, the story of Bangkok's Chinatown.

Tips for the Festival

Check the dates each year — the festival moves with the lunar calendar and usually falls in late September or October. Go in the evening, when Yaowarat is at its most atmospheric. Expect crowds, particularly around Wat Mangkon itself, which is the busiest point on the street during those nine days. Look for the yellow flag rather than asking each vendor. Wear something light-coloured if you want to fit in, white if you want to participate properly. And cover shoulders and knees at the temple, as at any working place of worship.

Nine Days Worth Planning Around

Wat Mangkon Kamalawat is worth seeing on any day of the year, but if your trip lands in late September or October, the nine days of the Vegetarian Festival turn the whole of Yaowarat into something no other city can show you.
