"Pai's khao soi benchmark - two sisters cook grandma's recipe, a rich coconut curry over egg noodles with chicken, beef or pork, for well under 100 baht."
Khao Soi Zisters is the bowl travellers walk out of town for in our Pai guide and a standout on the Thai map of the north. Run by two sisters - hence the name - at 58 Wiang Tai, a relaxed ten-to-fifteen-minute walk from Pai's Walking Street, it serves northern Thai food from their grandmother's recipes in a small, cosy room.
It is the kind of unpretentious specialist that earns a destination reputation on a single dish, and Pai's khao soi conversation tends to start here.
The signature is khao soi - the northern Thai coconut-curry noodle soup, a rich, gently spiced broth poured over soft egg noodles and topped with a tangle of crisp fried noodles, served with chicken (gai), beef or pork. Around it sit khanom jeen nam ngiao, the region's tomato-and-pork rice-noodle soup, plus Thai standards and a few vegetarian and tofu options. The recipes come from the sisters' grandmother and taste like it - homemade rather than tweaked for tourists.
Portions are generous, the spicing is honest, and almost everything lands for pocket change.
The room is small and easygoing, a handful of tables run by the two sisters, with a casual order-and-pay-at-the-register system that puts the food first. It is the opposite of a scene - calm, friendly and built for a quick, excellent bowl rather than a long sit.
It is a short walk out from the centre of Pai, open from morning into the early evening, and closes one day a week, so time your visit around the bowl.
Khao Soi Zisters is perfect for a solo lunch, a relaxed casual date, or an easy group bite in Pai. For other Pai tables, compare Charlie & Lek, Ganesh or Baan Pizza.
Not for a late-night dinner, a sit-down with table service or anyone after a refined, multi-course meal - it is a cash-friendly noodle shop that closes early.
