The restaurant Spectrum—previously known as Librije's Zusje—is situated within the Waldorf Astoria hotel in Amsterdam, Netherlands. This upscale dining venue has held two Michelin star ratings continuously since 2015.
Leading the kitchen is head chef Sidney Schutte, who has a background at "De Librije" and the former Librije's Zusje in Zwolle. Schutte returned to the Netherlands after his tenure at The Landmark Mandarin Oriental in Hong Kong.
The restaurant opened its doors on 1 May 2014 as the second sibling to De Librije. By September 2014, it was declared that the original Librije's Zusje in Zwolle would shut down by the end of that year, with De Librije assuming control of that site. In contrast to the original "Librije's Zusje," this Amsterdam location functions as a franchise rather than being under the ownership of Jonnie Boer.
In October 2018, plans were revealed for "Librije's Zusje" to become an independent entity and undergo rebranding starting 1 January 2019. After renovations, it reopened as "Spectrum" on 6 February 2019.
