Vietnam
Level 1 for its Buddhist ăn chay food tradition, considerably harder at conventional restaurants where fish sauce is near-universal and invisible on menus.
Level 1 is achievable throughout Vietnam with a dedicated ăn chay venue strategy. Fish sauce, shrimp paste, and meat stock require active navigation at every conventional restaurant outside dedicated Buddhist food venues.
The ranking explained Vietnam ranks 999 globally, a position driven almost entirely by the depth of its Buddhist vegetarian (an chay) infrastructure. The gap between city and country is significant: Ho Chi Minh City scores considerably higher at city level and appears consistently in HappyCow's global top rankings. Hanoi has a strong and growing dedicated scene. Outside these two cities and established tourist hubs like Hoi An and Da Nang, the ranking becomes considerably harder to leverage in practice.
The an chay tradition Vietnam's an chay (Buddhist vegetarian) food culture is the primary reason for the Level 1 ranking. Dedicated nha hang chay or quan chay (Buddhist vegetarian restaurants) operate in virtually every Vietnamese town and city, serving menus that exclude meat, fish, and seafood. Many serve fully plant-based food with no eggs or dairy. On the 1st and 15th of each lunar month, demand for an chay food surges and even venues that do not normally specialise in Buddhist food may offer chay dishes. Look for the words an chay or chay on signage: this is your primary navigation tool outside tourist areas.
An chay does not always mean fully vegan The an chay spectrum includes venues that are fully plant-based (thuan chay) and venues that include eggs and dairy (an chay trung sua). The distinction is not always visible from the outside of a restaurant. Always confirm whether a venue is thuan chay (fully vegan) before ordering. A venue describing itself simply as chay without further qualification requires this check. Always use the full exclusion list even at chay restaurants rather than relying on the label alone.
Always check labels Vietnam's food labelling standards are improving but allergen declaration is not mandatory in the way it is under European law. Always read ingredient lists on packaged products. Fish sauce and shrimp paste derivatives appear in many prepared sauces, condiments, and instant noodle seasoning packets. Never assume a product marketed as vegetarian is vegan without checking the full ingredient list.
What not to rely on Do not rely on dishes appearing plant-based without asking directly about fish sauce. Nuoc mam is invisible on the menu and present throughout traditional Vietnamese cooking at conventional venues. A dish with no meat on the plate may still contain fish sauce in the broth, marinade, or dipping sauce.

What Actually Works
Where It Gets Harder
Vietnam's Level 1 ranking reflects its an chay infrastructure, not its conventional cuisine. Step outside dedicated vegan and Buddhist vegetarian venues and the picture changes sharply: fish sauce, shrimp paste, and meat stock are the defaults at conventional restaurants regardless of what the dish appears to contain.
