From the concepts cradled by the critique of dispositives are discerned and analyzed the technical, pragmatic and symbolic (often overlapping) levels of the gastronomic opera "El Somni" (The Dream) proposed in 2013 by the brothers Roca and Fran Aleu. Thanks to this study, we observed that "El Somni" turns out to be a transgression of the traditional conception of gastronomy as a tool for obtaining pleasure or happiness through taste and a subversive dispositive that shakes the standard structures and the expectations placed on a meal, with which avant-garde cuisine transcends the merely alimentary to become an artistic language. And despite this, the diner keeps its socialization habits.
