The approach matters. You eat at Potong first – or at least you should – moving through Chef Pam Pichaya Soontornyanakij's Michelin-starred Thai-Chinese tasting menu in a Yaowarat shophouse that was, a century or more ago, her family's Chinese herb business. The building seems to know it. Then a tiny elevator takes you upward, two floors, and opens into a room operating on an entirely different register: dark, lacquered, quietly expensive, as though noise has been politely turned away at the door.
Opium is the bar above Potong, occupying the top two floors of a 120-year-old Chinatown shophouse that, according to its own legend, once operated as an opium den. The concept, developed by Arnon 'KK' Hoontrakul and described as ‘liquid surreality’, sets out to blur fantasy and reality. In practice, that means a menu of nearly 50 cocktails arranged across seven clear sections: aperitif, sparkle, acid, acid+, solo, duo and bottle infusions. The categories act as a navigation system, letting drinkers orient themselves without decoding every ingredient on sight. Italian bartender Matteo Cadeddu, whose résumé spans Australia, Singapore and Mumbai, leads a programme that rotates seasonally and earns its ambition.
Opium entered Asia's 50 Best Bars at No. 43 in 2025 and appeared on the World's 50 Best extended list at No. 92. It has also handled one particular challenge with grace: keeping pace with Potong below, where Chef Pam was named Asia's Best Female Chef in 2024 and World's Best Female Chef in 2025. Opium exists in that orbit without being swallowed by it – a bar worthy of the building, not merely adjacent to its reputation.
The drinker this suits: someone who wants a menu to think about, not one to rush through. A good date bar – the kind where you stay longer than planned.
422 Vanich Soi 1, Samphanthawong. Open Wed-Sun, 6pm-midnight.
