About 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.

  • Miang Goong

    Here you’ll be dodging scud chillies in the slightly sweet mountain of crisp school prawns, lemongrass, ginger, shallots, toasted coconuts, and ground shrimp, to wrap your own.

  • Three Flavoured Fish

    Fish was crispy and tender inside, the sauce was amazing - sweet, spicy & sour. Could do the sauce itself with a bowl of rice.
