Travel Guide
Northern Thai cooking often features peanuts, tree nuts, and fermented shrimp paste in ways that differ from the central Thai food many travelers know from Bangkok. Here is what to check as a food allergy traveler in Chiang Mai, and where to go if something goes wrong.
Chiang Mai, Thailand
Northern Thai dishes and their ingredient questions
Chiang Mai's food identity is distinct from Bangkok's. Lanna cooking uses fewer coconut-milk curries and more herbal, fermented, and roasted flavors, which changes the allergen picture in specific ways.
- Khao soi — egg noodles in a curry broth. Some versions include crushed peanuts as a topping or in the curry paste. Ask for the actual recipe, whether peanuts were cooked into the base, and whether the noodles, broth, garnish, and serving tools are separate.
- Sai oua — northern-style herbed sausage. Recipes vary by vendor; some include ground peanuts or shrimp paste in the binding. Worth asking about directly rather than assuming.
- Nam prik ong — a tomato and pork chili dip. Ask whether it contains kapi or another shrimp product, peanuts, nuts, and shared serving utensils.
- Gaeng hang lay — a Burmese-influenced pork curry. Recipes vary; ask about curry paste, peanuts, nuts, shrimp products, and any ingredients relevant to your allergy.
- Khan toke dinners — traditional multi-dish set dinners aimed at tourists. Convenient culturally, harder to control for allergies since you're served a fixed spread rather than ordering individual dishes.
Where to eat: markets, restaurants, and cafes
The Sunday Walking Street and the Chiang Mai Night Bazaar are the two biggest food destinations for visitors, and both are stall-based, meaning every vendor is a separate kitchen with separate practices. That's higher variability than a single restaurant kitchen, in both directions: some stalls will happily customize, others won't have the English or the flexibility to.
Chiang Mai has many cafes, including around Nimman, but menus, staff knowledge, and kitchen procedures vary. A Western-style menu may make the conversation easier; it does not guarantee that sauces, bread, shared fryers, or preparation surfaces are suitable.
For packaged food, supermarkets and convenience stores may offer products with labels you can inspect. Stock changes, so read the product in front of you and keep a backup meal rather than relying on one named branch or a product you have not checked.
For old town and market dining, a written Thai-language allergy card does more work than English ever will, since it removes the language gap between you and the person actually cooking, not just the person taking your order.
Build a Thai-language allergy card before you eat your first meal in Chiang Mai.

Frequently asked questions
Does khao soi contain peanuts?
It may. Some versions include crushed peanuts as a topping or in the curry paste. Ask about the actual recipe, whether peanuts were cooked into the base, and whether the noodles, broth, garnish, and serving tools are separate.
How is northern Thai food different from Bangkok food for allergies?
The cuisines use different recipes, so the questions change from dish to dish. In Chiang Mai, ask about peanuts, kapi or other shrimp products, nuts, curry pastes, sauces, and shared equipment. No city-wide comparison can tell you whether a particular stall or restaurant can manage your allergy.
How should I plan emergency care in Chiang Mai?
Save the route to the nearest current emergency department from each accommodation, carry your prescribed medication and action plan, and check current contact details before travel. For a life-threatening reaction, follow your plan, use prescribed epinephrine promptly, and call 1669 for emergency medical services. Do not delay care while trying to reach a named private hospital.
