If you have tried Pad Thai and Tom Yum Goong, there is much more Thai food to discover. In Chiang Mai you eat sticky rice with sausage, vegetables and dipping sauce, while in Isan people enjoy crunchy papaya salad and tangy fermented foods. Some dishes, like the noodles and snacks of Phuket, are specific to a city. Just as you might compare barbecue styles from region to region in the US, look for something new in the city you are visiting.
If Thai food is new to you, start with a bowl of curry or noodles with rice. With friends or family, order several dishes to share and try different flavors.
Thai table basics
Staple
In the Central region, meals are built around steamed rice with several dishes, while the North and Isan often eat sticky rice. Noodle dishes differ by region too.
What gives flavor
Chilies, herbs, sour ingredients, fish sauce and fermented ingredients are combined depending on the dish. The flavor makers are different from dish to dish.
Regions
This guide introduces the main traits of the Central, Northern, Northeastern (Isan) and Southern regions. Even within a region, the food of each city and community differs.
Dietary needs
Check the ingredients in seasonings and sauces too. You cannot tell from the name of a vegetable or chicken dish whether it is vegetarian or halal.
Looking at it region by region shows the flavors more clearly
Central Thailand
The Central table, where curry goes with rice
In Central Thailand, curries and several other dishes are eaten with steamed rice. The richness of coconut milk, sour, sweet and spicy notes come together differently in each dish. If you eat Tom Yum Goong and green curry in Bangkok, you can taste this combination of flavors.
The North, where sticky rice and vegetables come with dipping sauce
In the North, sticky rice and vegetables are eaten with nam prik, and the herb-scented sausage sai ua is a favorite. Khao soi in Chiang Mai puts noodles and curry broth in one bowl. Not all Northern food is mild, so ask about the spice level when you order.
Isan, with crunchy papaya and tangy fermented food
In Isan, try som tam and larb with sticky rice. Some dishes use pla ra, a fermented fish seasoning. Even within Isan, som tam differs in the chilies and seasonings used, so you can enjoy a different flavor from place to place.
The South, where seafood, noodles and many cultures meet
In the South you can enjoy spicy dishes, and also noodles and snacks that differ by city. Phuket has dishes shaped by Chinese and Malay food culture, and the Songkhla area has the food of Chinese and Muslim communities side by side. Pick the city you are visiting and explore its signature dishes.
First decide whether you want to share rice with several dishes or have one bowl of noodles.
Pick the meat, fish or shrimp you want, and tell the staff about anything you avoid, including seasonings.
Ask about spice level before you order. Broth or sauce that is already made may be hard to adjust.
When the food arrives, taste it first, then add extra seasoning and condiments a little at a time.
Frequently asked questions
Is all Thai food spicy?
Desserts and some dishes are not meant to be spicy. For curries and dipping sauces, you cannot judge the heat from the color or name, so it helps to ask before you order.
Do you only eat a regional specialty in that region?
Many dishes have spread and are eaten across the country. This guide explains links to regional food culture and does not claim a place of origin or an exclusive area.
Is a dish with vegetables vegetarian?
Some dishes use animal-based seasonings such as fish sauce and shrimp paste. If you have a dietary restriction, ask the staff to tell you the actual ingredients, including seasonings.
Tamarind's tang meets sweetness and salt. Eat the soft noodles together with bean sprouts and peanuts and you get a crunchy, nutty bite. At places that bring dried chili flakes on the side, you can add as much as you like.
Sour and spicy notes build on a broth that tastes of shrimp. Lemongrass, galangal and kaffir lime leaves give tom yum its distinctive aroma. Some versions are clear and others are rich, so dishes with the same name can taste a little different.
Behind the rich, smooth coconut milk, you taste the heat of the curry paste. The herb notes come through clearly, so it tastes quite different from sweeter, milder curries. Spoon a little curry and its pieces over your rice at a time.
The aroma of spices such as cinnamon, cardamom and clove runs through the curry. Eating it side by side with green curry, where the herbs stand out, makes the difference between the two easy to taste. Eat the thick sauce with rice a little at a time.
Sour and spicy seasoning meets the crunch of papaya. In versions with pla ra, a fermented fish seasoning, you can also taste a fermented aroma. Even with the same som tam, the taste changes with how the seasoning and chilies are used.
The sweetness of mango meets the richness of coconut. Sticky rice is chewy, so the texture is different from eating the fruit alone. Taste the mango and the rice separately, then try them together in one spoonful.
