This gem of a restaurant is something of a secret sensation in Barcelona. Listed in few guides, it caters mainly to clued-in locals who have fallen in love with chef-owner Robert Gelonch's relentless creativity and pursuit of perfection. It's worth making the effort to join them—the restaurant is off the beaten tourist track but still near the center of the neighborhood. Once there, depending on how hungry you are, expect to be astonished by a procession of small dishes from the short (€56) or long (€74) tasting menu. If you just want to dip your toe in the water, choose individual dishes from the "Moments of Madness" list. Some you will love, others you may not, but it is impossible to remain unmoved by the inventiveness and sheer talent on display here.
