Mama Kelly opens the doors of a new restaurant in Amsterdam's Olympic Stadium. CRHS provided project management from A to Z for this. Mama Kelly rents 1187 m² from the Bouwinvest Office Fund, which owns the commercial spaces and parking garage of the monumental Olympic Stadium.

The Olympic Stadium in Amsterdam-Zuid was specially designed for the 1928 Games by architect Jan Wils. The stadium was once on the list to be demolished, but was thoroughly renovated in 2000 and is now a national monument.

It is the second branch of Mama Kelly in the Netherlands, a restaurant known locally for the chicken and lobster on its menu. In the former boiler house of the Cabellerofabriek on De Binckhorst, the first restaurant opened in 2015. Mama Kelly is an initiative of Rein and Willemien Rambaldo, Singha Witteman and Bas Bloemink. Rein Rambaldo is also the owner and creative director of De Horeca Fabriek, an interior design and concept agency for the hospitality industry. He also designed the restaurant at the Olympic Stadium.
