Riverside rooftop at Millennium Hilton with 360° views, sunset rails, and a jazz lounge upstairs when the city lights come on.
ThreeSixty is one of those rooftops that slows your evening down. Perched on top of Millennium Hilton by the Chao Phraya, it’s split between an outdoor deck and an enclosed jazz lounge with wraparound windows. You come here less for hype and more for that feeling of watching the river change colour while someone else keeps your glass quietly topped up.
The outdoor terrace sits on level 31, high enough for a full 360-degree sweep of the river and skyline but still close enough that you can pick out ferries, barges and hotel boats sliding below. Around sunset, the water turns bronze, silhouettes move like slow postcards, and the city hums in the background instead of shouting. This is the moment to settle into a seat by the rail with something cold and not much on your agenda.
Later on, many guests drift upstairs into the circular jazz lounge. Floor-to-ceiling glass, plush seating and a central bar create that slightly old-school “cocktail hour” mood. On most nights there’s live jazz—singers, brass, brushwork drums—playing in front of a backdrop of lights stretching along the river. It feels polished but not stiff; people still talk, but the music sets the pace.
ThreeSixty runs with a classic rooftop-and-lounge formula, just executed with a bit more calm than most. The drink list is built around Champagne, wine and hotel-style cocktails—think Negronis, Martinis, Mojitos and sunset-friendly spritzes—plus a handful of signatures. Packages via partners like Hungry Hub, Klook and others often bundle two hours of free-flow drinks or snack-and-cocktail sets, which makes the pricing more predictable than walking in blind.
Food is mostly bar bites and international small plates: things you can share at low tables while watching the river rather than sit through a formal multi-course meal. Guests often pair ThreeSixty with dinner elsewhere—either downstairs at the hotel or across the river at ICONSIAM—then come back up for a last round and the jazz.
Dress code is smart casual: no flip-flops, sportswear or sleeveless shirts for men, in line with the rest of the hotel’s outlets. The crowd is mixed—hotel guests, couples on a special night, and Bangkokians who want a quieter alternative to the big “Instagram rooftops.”
