Anantara Siam Bangkok is a grand, classically Thai luxury hotel in the heart of the city's prestigious Rajadamri district. The hotel's architecture celebrates traditional Thai craftsmanship with hand-painted murals, gilded ceilings, and intricate wood carvings throughout. The Sunday brunch at Madison restaurant is legendary in Bangkok.
Anantara Siam Bangkok Hotel occupies a full city block on Rajadamri Road in the Pathum Wan district, directly facing the Royal Bangkok Sports Club racetrack and greenery. BTS Rajadamri station is adjacent to the building's entrance, giving direct Skytrain links to Siam (one stop), Ploenchit (two stops), and the riverside at Saphan Taksin. Central World and Gaysorn Village luxury shopping complexes are a three-minute walk north; Lumpini Park is accessible via the pedestrian overpass across Ratchadamri Road.
The hotel was established in the 1960s as the Siam Inter-Continental before Anantara took management and undertook a thorough repositioning toward traditional Thai luxury. The current interiors are dense with classical Thai artistic reference: hand-painted murals depicting scenes from the Ramakian epic, gilded teakwood ceiling panels, lacquered furniture inlaid with mother-of-pearl, and ceremonial floral arrangements at the lobby entrance refreshed twice daily. The property commits fully to Thai heritage aesthetics rather than gesturing at them.
Accommodation spans 354 rooms and suites with classical Thai design elements carried through all categories. Grand Pool rooms add private plunge pools looking onto the courtyard garden. Upper-floor rooms have views over the Sports Club grounds or the midtown skyline beyond Ratchadamri. All rooms receive morning fruit deliveries and silk turndown gifts on a rotating basis.
The Madison restaurant serves international cuisine and its Sunday brunch has been a Bangkok institution for well over a decade, drawing a loyal local following that books weeks in advance. Thai cuisine is served through a dedicated restaurant programme. The rooftop pool bar serves light lunches and sunset cocktails overlooking the Sports Club's greenery — one of the more peaceful elevated outdoor settings in this part of the city.
The Anantara Spa operates across two floors with traditional Thai massage, herbal compress treatments, and signature multi-day wellness programmes. The hotel's concierge team is well-versed in cultural itineraries — temple circuits, cooking classes, and facilitated access to events at the nearby Sports Club. The property is a frequent venue for diplomatic functions and large corporate events.
