If you have already tried pad Thai and tom yum kung, there is plenty more to find. In Chiang Mai, sticky rice comes with sausage, vegetables and a dipping sauce, while in Isan people enjoy a crunchy papaya salad and sour fermented dishes. Some foods, like the noodles and snacks of Phuket, change from city to city. Just as you might compare regional specialities at home, try finding a new flavour in the city you visit.
If Thai food is new to you, start with a curry or a bowl of noodles to eat with rice. If you are with friends or family, order several dishes to share and enjoy the different flavours together.
The basics of the Thai table
Staples
In the central region, rice is served with a range of dishes, while in the north and Isan sticky rice is eaten often. Noodle dishes differ from region to region.
Flavourings
Chilli, herbs, sour ingredients, fish sauce and fermented ingredients are combined according to the dish. What gives each dish its flavour differs.
Regions
This guide covers the main features of the central, northern, north-eastern Isan and southern regions. Even within one region, the food of each city and community differs.
Dietary needs
Look at the ingredients in the seasonings and sauces too. You cannot tell whether a dish is vegetarian or halal from a name such as a vegetable dish or a chicken dish.
Splitting Thailand into regions shows the flavours more clearly
Central
The central table: curries served with rice
In the central region, rice is served with curries and a range of other dishes. The richness of coconut milk, sourness, sweetness and heat come together differently in each dish. If you eat tom yum kung and green curry in Bangkok, you will taste that mix of flavours.
The north: sticky rice and vegetables with dipping sauces
In the north, sticky rice and vegetables are eaten with nam prik, and there is sai ua, a herby sausage. Chiang Mai’s khao soi puts noodles and curry broth in one bowl. Not all northern food is mild, so ask about spice when you order.
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 chillies and seasonings used, so the flavour changes from place to place.
The south: seafood, noodles and many cultures on one table
In the south you will find spicy food, and also noodles and snacks that differ from city to city. Phuket has dishes shaped by Chinese and Malay food culture, and the Songkhla area has the food of its Chinese and Muslim communities side by side. Choose the city you are visiting and look at its signature dishes.
First decide whether you want to share rice with a few dishes or have a single bowl of noodles.
Choose the meat, fish or prawns you like, and if there is anything you avoid, mention it including the seasonings.
Ask about spice level before you order. Broth or sauce that has already been made can be hard to adjust.
When the food arrives, taste it first, then add extra seasoning and side dishes little by little.
Frequently asked questions
Is all Thai food spicy?
Some dishes, such as desserts, are not spicy, and others do not stress heat. You cannot tell how hot a curry or dipping sauce is from its colour or name alone, so it helps to ask before you order.
Do regional dishes only get eaten in their own region?
Many have spread and are eaten across the country. This guide explains how a dish connects with regional food culture. It does not claim where a dish began or that it is sold only in one area.
If a dish has vegetables in it, is it vegetarian?
Not necessarily. Animal-based seasonings such as fish sauce and shrimp paste are sometimes used. If you have dietary requirements, ask for the actual ingredients, including the seasonings.
Sour tamarind meets sweet and salty notes. Soft noodles, then the crunch of beansprouts and the richness of peanuts as you chew. Where dried chilli flakes are served on the side, you can add as much as you like.
The broth carries the flavour of prawns, with sourness and heat on top. Lemongrass, galangal and kaffir lime leaves give tom yum its distinctive aroma. It can be made with a clear broth or a rich one, so dishes with the same name can taste a little different.
Behind the rich, smooth coconut milk you can feel the heat of the curry paste. The herb aroma is clear too, so it tastes quite different from a typical curry-house curry. Spoon a little curry and its pieces over your rice at a time.
The aroma of spices such as cinnamon, cardamom and cloves runs through the curry. Eating it beside a green curry, where herbs stand out, makes the difference between the two easy to taste. Have the rich sauce with your rice a little at a time.
The crunch of papaya meets a sour and spicy dressing. Versions that use pla ra, a fermented fish seasoning, also bring a fermented aroma. Even the same som tam changes in flavour with the seasonings and chillies used.
The sweetness of mango is joined by the richness of coconut. The sticky rice is chewy, so the texture is different from eating the fruit alone. Taste the mango and the rice separately, then bring them together on one spoon.
