Chat Thai has operated in and around Haymarket since the 1980s, growing from a single shopfront into a small chain of branches across the Sydney CBD and Thaitown, with the Campbell Street location remaining one of the busiest. The menu covers a wide range of regional Thai dishes rather than a narrow fine-dining selection, with boat noodles and pad thai the two most ordered items, alongside a strong dessert and Thai iced tea programme that draws a late-night crowd.

Sydney institution for authentic Thai food, with several branches across the CBD and Haymarket.

Chat Thai has operated in and around Haymarket since the 1980s, growing from a single shopfront into a small chain of branches across the Sydney CBD and Thaitown, with the Campbell Street location remaining one of the busiest. The menu covers a wide range of regional Thai dishes rather than a narrow fine-dining selection, with boat noodles and pad thai the two most ordered items, alongside a strong dessert and Thai iced tea programme that draws a late-night crowd. The dining room is simple and functional rather than stylish -- bright lighting, closely packed tables and a fast-paced, canteen-like service style suited to quick, no-fuss meals rather than lingering dinners. There is no wine list of note; the drinks focus is Thai iced tea, iced coffee and simple soft drinks rather than a curated beverage programme. Because Chat Thai does not take bookings at most locations, queues are common at lunch and on weekend nights, particularly given its reputation as one of Sydney's longest-running and most authentic Thai kitchens; arriving slightly outside peak times or opting for a quieter branch reduces the wait. Its long tenure in Haymarket, affordability and late opening hours have made it a reliable, no-reservation option for Thai food in the city.
