Pastry chef Carles Mampel has shelves full of trophies and medals, including one from Lyon in 2005 for his world champion chocolate cake. With bubó, he brings great pastry to the masses. This shop, in an alley near Santa María del Mar, in the heart of El Born, was his base for further expansion into other neighborhoods—and to Kuwait. If you don’t like chocolate, you can sample his carrot jelly swirled with coconut mousse and served with litchi ice cream topped with a hazelnut crunch. Of course, there are glittering macarons and chocolate confections, even sugar-encrusted marshmallow bonbons.
