Marquee AV Elevates Audio Experience at Kioku by Endo, Endo Kazutoshi’s New Japanese Restaurant.
Marquee AV is proud to announce the successful installation of a state-of-the-art audio system at Kioku by Endo, the latest culinary venture by renowned chef Endo Kazutoshi. Located in the iconic Old War Office Building, Kioku offers a unique dining experience that blends Japanese tradition with Mediterranean influences.
The Old War Office, a historic site that has witnessed significant events in the twentieth century, has undergone a remarkable six-year transformation. This prestigious location now hosts Kioku by Endo, a restaurant that reflects the cherished memories of Chef Endo Kazutoshi’s personal and professional journey.
Having previously collaborated with the owners of Kioku, on Humo in Mayfair; Marquee AV was once again entrusted to deliver a high-performance audio experience. The client, impressed by the quality of work at Humo, sought an even more advanced system for Kioku.
The whole installation covered the ground-floor bar set up as well as the 6th-floor and 6th-floor outdoor terrace and was piloted by Director at Marquee AV, Stacey Tough.

For the ground floor, Bose Professional DesignMax 3SE loudspeakers were selected and positioned throughout the Bar to provide full and consistent sound, supported by FreeSpace 3 Acoustimass bass modules to strengthen the lower frequencies.
The main dining area on the 6th floor boasts large windows offering stunning views of the Southbank skyline. The outdoor dining area wraps around the perimeter balconies, creating an elegant dining experience where guests eat amidst the rooftops of central London.
To match the beautiful scenery, Marquee AV’s team set sights on creating a sound system that was just as sophisticated as the dining arrangement and versatile to support a range of events.
Stacey opted for Bose Professional DesignMax 5 speakers, reinforced by hidden bass units, to maintain the sleek aesthetic and uphold impressive audio quality. The restaurant had also requested premium DJ equipment from Marquee, to be readily available without the need to hire equipment whenever they were hosting events. The Marquee team specified Pioneer CDJ3000 digital turntables, and a Pioneer DJM 900NSX2 mixer, stowed neatly in a custom flight case. The system also includes background music and DJ inputs, as well as twin mics discreetly concealed within the piano and a dual mic wireless system for vocals and instruments such as the cello or violin.
One of the building’s iconic turrets houses a private dining area, complete with its own turntable. The Pioneer PLX-500-K turntable is for clients to use which is connected to a pair of high quality HiFi speakers, adding a unique, personal touch and exclusivity to the audio and dining experience at Kioku.
Marquee AV’s commitment to excellence is evident in every aspect of this project. Stacey says, “The attention to detail throughout the restaurant, in the design and menu, was immaculate and we aimed to match this with the sound system. Working with the owners to understand their vision, we delivered a high-performing immersive audio experience that will elevate their live music events beautifully. From the intimate private dining areas to the expansive outdoor terraces, we have created a seamless sound environment that complements the restaurant’s sophisticated ambiance. We are thrilled to have contributed to making Kioku, a premier bar and dining destination in London.”
Marquee AV is proud to have worked in such an iconic building, bringing their expertise to enhance the unique atmosphere of Kioku by Endo.
