Meentzaal

Dudok Rotterdam has two separate rooms. The Westewagenzaal and the Meentzaal. The two rooms are identical and are connected by a corridor in the middle. The rooms have windows all around so you can look into the restaurant. 

When you reserve both rooms, the setup for a party is suitable for 72 people (instead of 36) and for a dinner 60 people (instead of 30).
