In fact, this easy to miss location is and the owner and chef, Sergio Mendoza Yebra is a native of Madrid, trained in European pastry techniques. I haven't found that many bakeries that offer pastries that are as beautiful and tasty as these. They offer both large and small versions of specialities such as the "Souffle" which has "Smooth lemon cream, a thin layer of vanilla cake, whipped cream with a touch of cinnamon sugar and caramelized lemon Swiss meringue on a buttery cookie shell." They also have Spanish cakes such as an almond torte, gorgeous, flaky croissants and meringues in a range of flavors and colors.
