Twin Brothers is one of the more established restaurants in the beachside strip at Surin, with a reputation built over years of serving straightforward Thai seafood to a mix of local regulars and visiting tourists who stumble across it. The cooking is southern Thai in style — spicier and more pungent than the central Thai dishes most tourists know, with a heavy hand on fresh turmeric, shrimp paste, and dried chillies.
The standout dishes are the grilled whole snapper with garlic and chilli, the crab curry cooked in coconut milk, and the green papaya salad prepared to order in the mortar. Service is unhurried, which suits the beach setting. The restaurant has a simple wooden structure open on all sides, and on a calm evening the table closest to the water is one of the better places to eat on this stretch of coast. Arrive before sunset if you want that table.
