Bangkok’s newest rooftop bar, Spectrum, has recently opened as a sparkling new gem in the crown of the city’s top-shelf night spots. Designed by the Japanese design firm Super Potato, the Hyatt Regency Bangkok’s new bar features a collection of cool, intimate spaces spread over three different levels. An intimate study room with a shared table is an ideal spot for a private dinner party with a floor-to-ceiling outlook on the city’s skyline, while the spacious living room entices guests to linger with deep, cushioned chairs and wooden tables spread out over a velvety blue carpet. However it's the alfresco terrace that spans level 30 and 31, that's the true drawcard and the best place to tuck into some wagyu beef sliders and a local craft brew while taking in the sprawl that is Bangkok.
