If you want an evening that is not another restaurant, Escape Club offers sixty minutes locked in a themed room with a chain of puzzles between you and the door.
The rooms vary in difficulty and theme, and staff adjust hints to the group. It works particularly well for couples and small groups; two people can finish a room, though four makes it easier. Games run in Turkish and English.
Book a slot in advance — walk-ins are rarely possible. Allow ninety minutes in total with the briefing and the photograph at the end.
From Romance Istanbul Hotel it is around fifteen minutes by taxi.
