The interior design for the Kit Kat Lounge & Supper Club envisions an opulent, theatrical, and atmospheric entertainment venue that creates a seamless transition between intimate dining and vibrant nightlife. The aesthetic is defined by a sophisticated base of rich wood paneling and plush, patterned armchairs, establishing a classic 'supper club' vibe. A key design element is the dynamic lighting scheme, featuring stepped ceiling coves with color-changing LED strips (shifting from warm ambers to deep blues and purples) that allow the mood to transform from a relaxed dinner setting to an energetic club atmosphere. The layout centers around two main focal points: a raised performance stage equipped for live music with a grand piano, and a glamorous bar area defined by a textured stone counter front and retro-style oval mirrors. Polished gold or brass railings and curved architectural lines guide the flow of the space, adding a touch of metallic luxury to the overall dark, moody, and exclusive environment.
