สินธุ์ Surat Thani

The origin. Closer to the tide, the river mouths, and the fishermen who supply every table SYNTH sets.

The Story

I

The Name

Named for Water. Born at the Gulf.

สินธุ์ — in classical Thai verse, the word means river, ocean, the great expanse of water. It was also the name of Chef Boss's grandfather: a man of the southern coast whose quiet dedication and deep knowledge of the land and sea became the seed from which this restaurant grew.

To name a restaurant สินธุ์ is to make a declaration: that everything on the plate will trace its lineage back to water — to the tidal flats of Surat Thani, the river mouths, the open Gulf of Thailand — and to the generations of southern Thai people who have lived by, and from, these waters for centuries.

Chef Boss

Before the restaurant opens, Chef Boss is often already at sea. SYNTH's relationship with the Gulf of Thailand is not a story told on the menu — it is the actual daily logistics of the kitchen. Chef personally joins local fishermen to source live catch, oversees the dry-aging of species that most kitchens overlook, and forages wild turmeric and herbs from the hills around Surat Thani.

SYNTH was among the first contemporary Thai restaurants to dry-age fish — a technique borrowed from Japanese kappo tradition and reinterpreted for Gulf species. Yellowfin tuna, grouper, mackerel, giant stingray: each treated with the patience usually reserved for great beef, developing a depth of flavour no fresh fish can match.

Source to Kitchen

Every ingredient traces back to a place.

We source directly. We know the fishermen, the tidal flats, the river bends, and the names of the people who provide them.

I fish because I want to know the fish. Not as an ingredient — as a creature that lived in specific waters, ate specific things. That knowledge changes how you cook.

What Our Guests Say

The Crab Betel Leaf Curry alone is worth the trip from Bangkok. You can taste that the crab came fresh from Surat Thani — the crab roe curry is rich, complex, and unlike anything in the city.
