At the beach pavilion At Sea on the Drontermeerdijk in Dronten, a surprisingly excellent escape room was hidden in the restaurant for years: De Collectie van Dr. Bahrenheit. The story revolved around ex-surgeon Fritz Bahrenheit, who after early retirement built one of Europe's most impressive private art collections — allegedly including paintings looted in WWII — and only let guests in 'under strict supervision'. Visitors were remarkably enthusiastic (9.1/10 on escaperoomsnederland): thrilling from start to finish, varied and challenging puzzles, staff who played along with the story, and coffee with pastries upon arrival. The room quietly disappeared around 2025 — after a substantial Social Deal discount in late 2024 — and no longer appears on the current At Sea website; the restaurant itself remains open.
