The Nave 9 cafeteria is run by Carlos Romero, a renowned figure in the Bilbao music scene, who also programmes the music at Itsasmuseum.

Apart from its role as a cafeteria, Nave 9 also provides customised catering services for many of the corporate events staged at Itsasmuseum.

The museum features a new kind of shop, located in the atrium by the ticket office. Visitors can purchase personalised items and publications released by Itsasmuseum as part of its remit to extend knowledge of maritime matters.
