What to Eat in Thailand: A Region-by-Region Field Guide

There Is No Such Thing as "Thai Food"

Ask for "Thai food" and you've asked for nothing. The dish that defines a Chiang Mai lunch would be a stranger on a table in Hat Yai. The salad that an Isan grandmother pounds with thirty bird's-eye chilies is not the timid, sugar-forward som tam you got at a hotel buffet. Thailand is four regional cuisines wearing one flag, and the single most useful thing a hungry traveler can learn is to stop ordering by country and start ordering by region.

I've eaten my way across all four over the better part of a decade on assignment, and the map below is how I'd spend a first trip. Prices are mid-2026, and a baht runs around 36 to the US dollar. Where I name a stall, it's because I've sat at it more than once. Where I name a region, it's because that's where the dish is doing its most honest work.

Bangkok: The Stall Is the Restaurant

Bangkok is a port city's cuisine, Chinese-Thai at its spine, and the street is where it's most alive. Start with boat noodles (kuaitiao ruea) at the canalside stalls off Victory Monument on Soi Rang Nam, where bowls run 15 to 20 baht ($0.40 to $0.55) because they're sized for stacking. The broth is dark, beefy, thickened with blood, sharp with star anise. Order four bowls. Everyone does. The pile of empty bowls is the point.

For pad thai, skip the hostel version and go to Thip Samai on Maha Chai Road, the standard-bearer since the 1960s. The signature wraps the noodles in a thin egg crepe; the prawn-oil version runs around 120 baht ($3.30). It's sweeter and more delicate than the dish's global reputation suggests, because pad thai was always a refined noodle, not a peasant one. A few doors down, Jay Fai still fires her crab omelette over charcoal in ski goggles; the Michelin attention pushed it to 1,000 to 1,500 baht ($28 to $42) and a long wait, but the drunken noodles are the smarter order if you want to understand the cooking rather than the legend.

Isan: The Northeast Punches Hardest

Isan, the dry northeastern plateau bordering Laos, is the most influential regional cuisine in the country and the one most travelers underrate. This is the home of som tam (green papaya pounded in a clay mortar with lime, fish sauce, palm sugar, long beans, tomato, and a fistful of chilies), of larb (minced meat tossed with toasted rice powder, lime, and herbs), and of gai yang, charcoal-grilled marinated chicken that's better than almost anything fancier.

Eat it in Khon Kaen or Udon Thani if you can, where som tam pla ra — fermented-fish-sauce version, funky and uncompromising — is the default rather than the dare. A full Isan spread of som tam, gai yang, and sticky rice runs 120 to 180 baht ($3.30 to $5) per person. Sticky rice (khao niao) is the utensil here: pinch a ball, dimple it, scoop. The toasted rice powder in good larb should smell nutty and faintly smoky. If it doesn't, the kitchen skipped a step.

The North: Lanna, Khao Soi, and the Burmese Border

Northern (Lanna) cooking is milder, herbier, and shaped by inland geography and Shan-Burmese trade. Its signature is khao soi: egg noodles in a coconut curry broth, topped with a crisp tangle of fried noodles, served with pickled mustard greens, shallots, and lime. In Chiang Mai, Khao Soi Khun Yai (open lunch only, often sold out by 13:00) and Khao Soi Lam Duan on Charoenrat Road both do honest versions for 50 to 70 baht ($1.40 to $2). The broth should be rich but not gloopy; the fried noodles should still crackle when the bowl reaches you.

Build the rest of a northern meal around sai ua, the lemongrass-and-kaffir-lime herb sausage grilled over coals, and nam prik num, a roasted green-chili dip eaten with steamed vegetables and pork rinds. These are the textures of a Lanna khantoke spread, and they're nothing like the curries of the South or the salads of the Northeast. The North whispers where Isan shouts.

The South: Where the Curries Get Serious

Southern Thai food is the hottest in the country and, for my money, the most thrilling. The peninsula's Muslim and Malay influences and its access to the sea produce gaeng tai pla (a pungent curry built on fermented fish innards), khua kling (dry-fried minced meat with a turmeric-and-chili paste that will rearrange your sinuses), and the gentler massaman, a Persian-descended curry of beef, potato, peanut, and warm spice that's the deserved global ambassador of the region.

Eat in Trang, Krabi, or Hat Yai, where Hat Yai fried chicken — marinated, fried hard, scattered with crisp shallots — is a religion, often under 60 baht ($1.65) a plate. A southern curry-rice shop (khao gaeng) lets you point at five or six pots and pay 60 to 100 baht ($1.65 to $2.75) for a loaded plate. Order rice first, then point. The chili here is not decorative; ask for "phet noi" (a little spicy) and brace anyway.

Markets vs. Restaurants: How to Actually Eat

The honest answer is that Thailand's best cooking is mostly informal. A specialist stall that makes one dish a thousand times a week will out-cook a tourist restaurant attempting forty. For breadth in one sitting, a night market — Chiang Mai's Sunday Walking Street, Bangkok's Or Tor Kor (a fresh market with a stellar food court) — lets you graze across regions cheaply. For depth, find the single-dish specialist with the long local queue and the laminated photo of a royal visit.

A few rules I'd stake my name on: a busy stall means fast turnover and fresh ingredients; a stall that's emptied its pots by early afternoon was probably worth the morning trip; and the gaeng (curries) sitting in trays at a khao gaeng shop are made fresh at dawn, so eat them at lunch, not dinner. Sit-down restaurants earn their keep for seafood, for air-conditioning in April, and for the rare ambitious kitchen — Bo.lan in Bangkok or Samuay & Sons in Udon Thani — doing regional cooking with real intent.

The Sweet Ending Worth Saving Room For

Mango sticky rice (khao niao mamuang) is the dessert that deserves its fame, but only in season — roughly March to May, when nam dok mai mangoes are at their honeyed peak. Out of season you're paying for cold-storage fruit; in season, a portion of warm coconut-soaked sticky rice with ripe mango and a scatter of toasted mung beans runs 60 to 120 baht ($1.65 to $3.30) and is one of the great cheap pleasures on earth.

Beyond it, chase roti from a Muslim-Thai griddle cart in the South, kanom krok (coconut-rice custard half-spheres) from a market griddle, and any tray of vividly colored kanom (steamed sweets) you don't recognize. Thai sweets are a separate craft from the savory kitchen, and the good ones are getting harder to find as the cart vendors age out — eat them while they're still made by hand.
