The visitor experience begins on the street-level elevator lobby entrance enveloped by a hand-painted mural.  On the rooftop, a steel-framed, open-air pergola structure with an Ipe wood ceiling houses the bar. The bar features a luminescent quartzite top over a vibrant green base composed of handmade tile.  Completing the tropical look are woven light pendants and framing the back bar’s wood shelving is a custom metal screen designed with Modern Metal Designs, whose abstract pattern is a subtle nod to the KAIYŌ logo.

Elsewhere, the seating options are varied and flexible, and include built-banquettes. The tropical ambience is enhanced by nature-inspired, drought-friendly features such as a manufactured green wall.  These richly textured design elements create a cross-cultural vibe that feels at once appealingly familiar, and intriguingly exotic.

The project’s technically challenging parameters notwithstanding, the resulting fusion of cuisine, design and architecture is an aesthetically well considered journey into another world.
