Biography

Early years

Career

Castelló cooked at Paco Pérez's Tast restaurant and at Pep Guardiola's restaurant in Manchester before joining Miquel García to launch Insolent in Barcelona's Gràcia. The four partners — Castelló and García in the kitchen, Javier Custodio and Pedro Huerta on the dining-room side — describe their cooking as 'territory cuisine that combines tradition, technique and a special creative sensitivity to offer seasonal, flavorful and surprising dishes.'

The restaurant is in the Michelin Guide selection.
