Coqodaq uniquely integrates lighting into its interior. Executive chef Seung Kyung Kim leads the restaurant, blending art nouveau and Korean design in an opulent space with bespoke furniture and curated lighting. The dining area features communal and high-top tables, with "ghost" arches of cast glass adding intrigue. The entry with the unique washrooms carries the geometric lines that stems from the restaurant's logo to create an iconic moment as the first of several special lighting moments. The communal tables are anchored on one end by wall shelves that have only indirect lighting to illuminate glassware but also provide indirect lighting to the space. The main bar runs the length of the main dining room and carries suspended linear pendants. The series of large glass arches that lead guests through the main dining room provides the general sense of brightness and is supported by recessed downlights to highlight each tabletop. The banquet booths have fixed table lamps and low level step lights to provide a human scale of glow and lighting that is especially noticed when the room is darker during late night settings. The wine room is also illuminated in an unconventional way using suspended strings of glowing lights that mimic the bubbles rising up a champagne glass. The use of strong geometric light sources is creatively layered with indirect and diffuse sources of light to ensure that the graphic arches and lines of light do not become sources of glare or discomfort for both restaurant guests and staff. A concentration of light on food and ambient lighting layers create contrast and also a conservative use of light and energy. The lighting control system conserves energy by programming lights to turn on, off, or dim based on the function, such as lunch, early dinner, later dinner, after hours, etc.
