"Spectrum (formerly Librije’s Zusje) is an outstanding two-Michelin-starred restaurant. Chef Sidney Schutte produces exceptional food with imaginative, often highly unusual flavor combinations, like Dutch lobster with duck tongue and duck liver, licorice, green apple, and pistou. The attention to detail both on the plate and in the dining room is exquisite. A meal here is absolutely worth the splurge." - Monique van Loon
