Our largest venue is the Grand Ballroom. Outlined in elegant crown molding and awash in calming, neutral hues, it is ideal for conferences, lectures, or grand affairs. The expansive space can accommodate up to 600 guests theater-style or be divided into two distinct spaces, with four possible configurations. Additionally, the ballroom foyer can be divided to ensure both Ballroom A and B have their own private pre-function area.

Meanwhile, on the 25th floor, Altitude comprises an indoor function space, an elegant breakout room for 20 called The Library, and an outdoor terrace for up to 50 guests, with a dramatic panorama of downtown Bangkok. Outfitted with ornate patterns, Thai influences, and bold pops of crimson, these picturesque spaces can accommodate up to 250 guests for a meeting or evening cocktail reception. An engaging open kitchen further enhances the stunning setting.

For smaller gatherings, Botan, which means "peony" in Japanese, can host up to 40 guests theater-style or be divided into up to four separate rooms for even more intimate occasions. Connected to Kisso Japanese Restaurant, it allows for working lunches or dinners-and also features a foyer area for coffee breaks.

Formal meetings can also be held in our eighth floor meeting rooms, which share a pre-function area, or in our boardroom, which is bathed in natural light.

Additionally, the pool deck provides an enchanting backdrop for evening events, such as cocktail receptions or dinners of up to 50 guests. Daytime events can also be accommodated December through February, when the climate allows.
