Grotto functions as a pavilion with modest catering facilities.

The kitchen and furniture are by designer Olav Koreman (Breda, 1959, lives and works in Molenschot and Breda), in a typically Dutch tradition (De Stijl), but also with references to Minimal Art of artists including Sol LeWitt. Using minimal means, Koreman has achieved maximum effect both inside and outside, while at the same time leaving the complex character of Grotto completely intact.
