Book NowAbout Caysorn Thai
Perched on the first floor of Haymarket’s Prince Centre, Caysorn builds its name on Southern Thai cooking that refuses to dial down the heat. Thai diners pack the tables for regional Phattalung specialties rarely spotted on suburban menus. The kitchen leans straight into sour funk and sharp chili—particularly in the Gaeng Som Pla, a tamarind fish curry with crisp papaya that leaves the tongue buzzing. Plates revolve around *kanom jeen*, soft fermented noodles ladled with coconut-fish gravy and balanced by pickled greens from the salad bar. It is a clattering, BYO-friendly room where an ice cream cart waits by the register when the spice kicks in.
- Regional Phattalung Heat: Phattalung-style curries like Gaeng Som Pla and dry-spiced Kua Kling arrive packed with intense tamarind tartness, shrimp paste, and full chili heat.
- Fermented Rice Noodles & Veg Bar: Six variations of soft fermented rice noodles served alongside a help-yourself bar loaded with fresh herbs and pickled vegetables.
- Balcony Seating & BYO: A relaxed, bustling first-floor space with balcony tables, low corkage BYO, and a sweet coconut ice cream cart to cut the burn.

Before you head over
Essential advice on managing uncompromising Southern Thai spice, maximizing noodle pairings, and planning your visit. Book your table now to secure a spot.
Calibrate the Regional Heat
Southern Thai specialties marked with chilli icons—like the three-chilli jungle curry or Gaeng Som Pla—pack intense heat that can numb your palate. If you are sensitive to extreme spice, ask staff to turn it down a notch, or order sticky rice and visit the on-site ice cream cart to soothe the burn.
Balance Curries at the Salad Bar
When ordering fermented rice noodle curries like kanom jeen nam ya kati, take full advantage of the restaurant's salad bar. Piling up on fresh greens and pickled vegetables adds crisp contrast and balances the pungent, rich curry sauces.
Navigate Dinner Crowds and BYO
The dining room fills up fast during evening services and Friday nights, which can stretch the floor staff. Take advantage of their casual BYO policy ($3.50 per person), and make sure to book your table in advance to avoid waiting.
