Sergi Arola, a stellar Catalan acolyte of the world-renowned chef Ferran Adrià, runs this highly personalised temple to all that’s innovative in Spanish gastronomy. The menus change with the seasons – a recent sample included smoked beetroot raviolis with celery consommé, or Jerusalem artichoke soft cream, truffled poultry mousse, mascarpone cheese and fine herbs. You pay for the privilege of eating here. But this is culinary indulgence at its finest, the sort of place where creativity, presentation and taste are everything. And oh, what tastes…With just 26 seats, booking well in advance is necessary.
